How power produced by a solar cell is affected by its distance from a light source. Theory I expect that as the solar cells are moved closer the light source the higher the power they will produce. As light moves away from the source it spreads out at all angles the further you are from the source the less intense the light will be. P = I V Power = current x volts P = FA Power = flux x area Flux = P/A Area of 4 solar cells that I will use is 0.0077m2 This means
Investigating How the Size of a Shadow Depends on the Angle at Which the Light Hits the Object Introduction ============ The aim of the project is to see which factors affect the size of a shadow and then to look more closely at one of the factors to see how exactly it varies the size of a shadow. Variables that may affect the size of the shadow ================================================ Although, I will investigate how one factor affects the size of a shadow, there
Photosynthesis Investigation to find effects of distance of a light source from pond weed has on the amount of oxygen produced Photosynthesis All green plants need to be able to make their own food.They do this by a process called photosynthesis.For photosynthesis to occur they need sunlight energy.This energy is absorbed by a green pigment called chlorophyll,which is mainly found in the leaves.This energy then combinEs with water molecules (from the soil) and carbon dioxide (from the air).Then
The Effect of Intensity on the Power of Solar Cells This experiment involves changing the intensity of light falling on different cells and measuring their power outputs. Higher intensity of light means that there are more photons hitting the surface of the cell per unit area per second. The more hit the cell, the more rapidly the electrons move across the p-n junction, so the larger the emf produced. If the rate of movement of electrons is inhibited, then the greater
Renaissance Art The term renaissance, describing the period of European history from the early 14th to the late 16th century, is derived from the French word 'rebirth'. This period is described as the revival of the classical forms originally developed by the ancient Greeks and Romans, and an intensified concern with the secular life--interest in humanism and assertion of the importance of the individual. The renaissance period in art history corresponds to the beginning of the great western
impressed with the thought that Rembrandt touched the same canvas that I was viewing almost four hundred years ago. The painting serves as a direct link into the past; a past that is remarkable for all it accomplished. A wonderful artistic example of light contrasting with dark, “Old Man in a Military Costume” is a remembrance of how closely connected we are with the past. When artists or historical figures are merely memorized names, they lose some of their impact; experiencing part of their lives reminds
Madam Matisse: The Green Line Henry Matisse, one of the most influential members of the Fauve movement, was responsible for much of the attention brought to it and its respective members. One of his works, Madame Matisse: The Green Line, more or less serves as an excellent example of what he was trying to accomplish in art: the use of color to express and convey emotions. The composition of the work consists of a portrait of Madame Matisse in the foreground and a background divided into
How Light Affects the Stomatal Opening in a Leaf Abstract ======== My aim of this investigation was to check the affect of environmental factors affecting stomatal opening. My experiment was designed to check the stomata opening in light. Plants move in ways that may not seem obvious. The opening and closing of stomata is one example of this movement. There are a large amount of growth conditions that can affect a plant. One of the most important of these conditions concerns the
An Investigation into the Effect of Light Intensity on the Rate of Photosynthesis on a Piece of Elodea Plan: Method: 1) First I will put some water into a boiling tube and add 5 spatulas of Sodium Hydrogen Carbonate. I will add 5 spatulas of Sodium Hydrogen Carbonate as it reacts with water and forms carbon dioxide; also I have so much so that I have carbon dioxide in excess. 2) Then I will cut off 5cm of elodea and place it into the boiling tube. 3) Thirdly I will place the boiling
photosynthesis when pondweed is under different life intensities. Prediction: I predict that the closer the light is to the pondweed the (or the higher the light intensity) the more oxygen will be produced until a certain point where the temperature or carbon dioxide levels will be the limiting factor. The further away the light, the slower the oxygen bubbles will be produced so the less light the less photosynthesis will occur which is needed for the plant to make food. [IMAGE] The rate increases

a pure coherent light source, the laser became available in 1963. The techniques of holograms are also applicable to sound, and bats may navigate by ultrasonic holography. Holographic techniques also have applications in storing dental records, detecting stresses and stains on construction and retail goods, detecting forged paintings and documents, and producing three-dimensional body scans. Holography is a method of producing three-dimensional images by means of laser light. Holography uses
give the twisting motion. The fingers will be able to grab an object. Some people use grippers. The grippers work like sicorrs. There are also devices that act like sensory nerves. These devices are either light sensitive or switch activated. That way a robot would be able to tell where a light source is coming from or when it was running into a wall. The hardest part about making a robotic hand do something is to make the open and closing motion with the fingers. Humans have nerves and muscels that
Analysis of Gerrit van Honthorst's Painting, Musical Group on a Balcony The Dutch painter Gerrit van Honthorst was known in Rome as Gherardo delle Notti (Gerard of the Night Scenes) for his striking use of a single light source to illuminate a dark scene. He was successful in bringing Caravaggio’s lighting techniques with him to the North, influencing many painters, including Rembrandt. But his painting “Musical Group on a Balcony” is a departure from his customarily dark depictions. This piece
voltage is affected when exposing different sized areas of a solar cell to a light source. From this I will also establish the energy of each photon and approximately, the number of freed electrons, which can make an electric current flow. I know that light consists of packets or quanta of energy called photons. When electromagnetic radiation such as light shines on materials (usually metals), which emit electrons the light photons containing energy are captured by the electrons. This means that
The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While Photosynthesis is Taking Place Hypothesis: I predict that as the intensity of light is increased, so would the photosynthesis. Furthermore, I predict that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase. However, the lower the light intensity, less oxygen will be produced which would
rays of the sun were disappearing over the horizon. There are a few clouds in the sky, they are dark but not threatening. The picture is very dark in general and there is no obvious light source. The edges of the painting are so dark it is impossible to tell what the nude reclines against. A very dim light falls on the woman, who lies on her right side. The upper half of her torso is twisted to her left and her hips and legs face the viewer. Her right leg is bent slightly so her calf is
this time Young's primary focus was sense perception, it was during this time that Young concluded that astigmatism results from an improperly curved cornea. It was also during this time that he turned to the study of light. During the 17th and 18th centuries, the nature of light was one of the mo...
Missing Figures Characteristics of Light There are a few fundamental characteristics of light that are useful to be aware of before proceeding with the discussion on how CCD's and Film can function to save a useful, meaningful image. One of these important fundamental qualities is the fact that visible light is electromagnetic radiation. Electromagnetic Radiation, Photons, and Energy Levels Electromagnetic radiation has many different classifications. Some such classifications include
Comparing the Light and Electron Microscope In this essay I am going to be comparing the light and electron microscope, I will look at the advantages and disadvantages of each microscope and then analyse my findings to see if one is better than the other. The light, or optical microscope as it is also known was invented in the 17th century, it has been refined in many ways over the years but it is essentially still the same. The light microscope works by; light rays
