LIGHT: A FUNDAMENTAL FORCE IN OUR WORLD
If asked what light is, one could say that it's one of the most basic
elements of our world and our universe as we perceive it. It is through
sight that we receive 90% of our information. It is through the use of
telescopes aiding the naked eye that we are aware of the heavenly bodies
around us. It is through light that the energy from the sun is transferred
to us. The sun's energy supports the food chain; plants use it to turn
water and CO2 into energy usable by other organisms. Solar energy was also
used, indirectly, to produce all of the fossil fuels that we consume daily.
Since light is such a basic part of our existence, we should have a basic
understanding of what it is.
What we call light, the intangible, powerful force that powers our world,
is somewhat hard to define in real terms. It shares properties with both
particles and waves. It follows the same rules as a wave does--it moves in
a regular fashion, in a perfect sine wave at a certain frequency. It
travels in a straight line, and is subject to refraction. All of these
characteristics are found in waves of any type, from radio frequency waves,
up to Gamma and X- rays. Light, however, also exhibits qualities
characteristic of particles such as neutrons and protons. A photon, or
quanta, is the "packet" of energy that is sent in a light wave. Like a
particle, the photon is believed to have a fi...
Introduction Light is important for our daily life in order to see in darkness or to capture a perfect picture. Back in B.C century, people use a Sun as a source of light and at night they use a fire or touch to see in the darkness. In photoshoot or in event lightning is one of the most important equipment to have to take a picture or record a video. Some of the lightning can be use in a wedding, concert or event it better quality for videos and pictures or for the vision. There are variety of lightening
Light has three principal characteristics that affect plant growth: quantity, quality, and duration. Light quantity refers to the intensity or concentration of sunlight and varies with the season of the year. The maximum is present in the summer and the minimum in winter. The more sunlight a plant receives (up to a point), the better capacity it has to produce plant food through photosynthesis. As the sunlight quantity decreases the photosynthetic process decreases. Light quantity can be decreased
Since the dawn of man, light has been a point of interest. For centuries man has studied light and its effects in the world, and for a long time we were oblivious to how it truly worked; but thanks to a young scientist, name Thomas Young, we learned how it worked in the early nineteenth century. Light, as it turned out to be, is a wave particle rippling through the universe. The purpose of this essay is to explain Young’s findings and the experiment he used to learn how light worked. During the centuries
surge of pain throughout his whole body. His eyes feel too heavy to open, but he forces them to. The bright lights blind him momentarily, but his eyes adjust a few seconds later. He sees two men dressed in suits hovering above him. He is quickly frightened when he realizes that in place of their eyes is nothing but darkness. The last thing John feels is a pinch in his left forearm and then the light is gone. The next time John opens his eyes, he's in a different place. It's a small room with not much
Light consists of electric and magnetic fields, commonly known as electromagnetic waves. These waves are generated by the movement back and forward of electric charges, or oscillation. The term light is commonly referred to just those electromagnetic waves that we are able to see. Light can only be visible when it has a wavelength within a narrow range of values called the visible spectrum, if the wavelength is too long or short, it is a different kind of wavelength in the electromagnetic spectrum
By looking at Table A in the microscopic light results, it can be seen that the results would obey the inverse square law. This was because as the distance increases the light intensity of the microscopic light decreases. The graphs that demonstrate the inverse square law can be seen in figure 1 and 3. Thus, it is evident that the relationship between light intensity varies inversely with the square of the distance holds truth in real-life situations and or under laboratory conditions. The reason
your eyes. Light affects how we see things around us. Thomas Edison designed the first-long lasting incandescent light bulb in 1879. Light travels in waves and is emitted from a source. The sun gives of Visible and Ultraviolet light. Light waves have peaks and valleys. The peaks and valleys have wavelengths. It depends on the type of the light. There is light on an Electromagnetic spectrum and it has all types of different lights. The Electromagnetic
another issues to care but in fact energy cannot be replaced so the most important now is think forward and find solutions. Light control is a market which is growing up and has a lot of benefits. It's essential not only to innovate and save energy but also to make easy a life of a people bringing facilities, comfort and security. As yours needs during the day, the light can adapt on the way you want which means that will create a comfortable atmosphere and less stressful. In fact, it's a combination
The Northern lights are poetry, they are nature's light show, and they are quantum leaps in the oxygen atom. They are elementary particle physics, superstition, mythology and fairy tales. The northern lights have filled people with wonder and inspired artists; they have frightened people to think that the end is at hand. More exact explanations of the phenomenon could not be given until modern particle physics were developed, and knowledge about details in the earth’s magneto sphere has been based
believe that some people have light while others have to ‘borrow’ it. This concept of borrowed light is a main driving factor of the novel Borrowed Light as Callisto’s belief that she needs to be around bright people and make them happy leads to her pregnancy. Her need to borrow light is shown in her relationships and how she feel about herself and her identity and these themes in Borrowed Light reveal this. Relationships throughout the novel show one person borrowing light from the other and how that
Light: the quantum phenomenon that provides luminous energy for our world. Radiant energy is why we can observe a twinkling star in the night sky, perceive colors from a painting, distinguish daytime and nighttime, and witness life itself. However, the concept of light is difficult to digest. Many questions about it are yet to be pondered, and most existing ones require technology beyond your and my reach to answer. But we can prove something without much modern tools: manipulation of light. Manipulation
What exactly is light? Is it a wave? Is it a particle? Is it a mythical being? This question has been debated on for many centuries. Some claimed it was a wave. Others claimed it was a particle. In the early nineteenth century, Isaac Newton proposed that light was made up of particles, but the answer was not agreed on until an experiment performed by Thomas Young. Young’s basic experiment consisted of a coherent light source such as a laser beam being shot through and illuminating a plate containing
The Visible Light Spectrum “Mr. Petersuh-uh-uhn…. I need a white crayon for the white parts of the map!”, my daughter’s classmate whines as she peers into her box of mismatched Crayons. “Don’t worry about coloring those parts of the map. White isn’t a color anyways…”, replies her sixth grade teacher. Uh-oh. Big mistake! The entire class is now in for an impromptu lesson in the properties of light and the visible spectrum, courtesy of the child of a laser student. Added bonus: elevated egg-headed
Light is a source of power for all things on earth. Whether it be humans, animals, or plants all need light in order to live and prosper. However, light does not just come in the form of waves and particles, but also comes in the form of the light of the Gospel. Heavenly Father and Jesus Christ have provided us with light which leads and guides us in our lives. It is through that light that we know what is right, and what Heavenly Father wants us to do. The principle that I will be examining in this
In the light intensity experiment, tubes of buffer solution, chloroplast, water and DPIP were placed in different intensities of light to determine how light intensity affects the reaction rate of photosynthesis. The reaction rate was measured by absorbance values in five-minute increments for 30 minutes. The tubes were placed at 24 cm away, 30 cm away, 49 cm away, and completely dark. The tube that was closest to the light had the smallest absorbance value, while the dark tube had the highest value
