• ## Mathematics of Lenses and Optical Glass

1931 Words  | 8 Pages

Missing figures PROPERTIES OF LENSES, OPTICAL GLASS Composition Glass is a solid, structureless and amorphous. There are two main group classification of optical glass: 1. Crown, and 2. Flint (has a high content of lead oxide) Chemicals are combined to produce new glass types. These new glass types are used to benefit other different types of cameras (such as high-speed minature cameras, black/white cameras, etc). Properties The most important optical characteristics of a glass

• ## Relationship Between the Resistance and the Length of a Wire

920 Words  | 4 Pages

Relationship Between the Resistance and the Length of a Wire Aim: To find the relationship between the resistance of the wire and the length of the wire Background Factors: i. Temperature : If the wire is heated up the atoms in the wire will start to vibrate because of their increase in energy. This causes more collisions between the electrons and the atoms as the atoms are moving into the path of

• ## The Effect Length Has on a Pendulum's Period

507 Words  | 3 Pages

The Effect Length Has on a Pendulum's Period Prediction: I predict that the shorter the length of string, the shorter the time it takes for the pendulum to complete one period. The longer the length of the string, the longer the time it will take to complete one period. Equipment needed for experiment: -Clamp -Stopwatch -Bob/Ball -Metre ruler -String Obtaining the results: I will be measuring the length of the string in 10s, so that I can obtain a wider range of

and still produce frame-filling shots while minimizing the amount of background distractions. Furthermore, they're extremely sharp and fast — ideal for low-light conditions. Zoom lenses such as the 28-105mm f/3.5-4.5 USM, which include these focal lengths, work well in situations where you have a bit more available light. In situations where you want to interact with and control your subject, and minimize the effect of your background, short-to-moderate telephoto lenses may be the ideal choice. Longer

• ## Investigating the Length of Words in Magazines and Newspapers

557 Words  | 3 Pages

Investigating the Length of Words in Magazines and Newspapers Introduction In this piece of coursework I am going to look at the differences between articles from newspapers and magazines. I will be looking at the length of the words in each of the articles to see which of them has the longest words. Plan I am going to take a 100 word article from both newspaper and magazine. The article that I have chosen from the newspaper is out of “The Evening Telegraph”. The article that I have

• ## Investigating the Length of Long Shore Occurence

1038 Words  | 5 Pages

Investigating the Length of Long Shore Occurence Reason for study: to find out if long shore drift occurs and if it does, to find defences to prevent any hazards The place of my study was porlock bay in Somerset. This is a picture of the porlock bay. [IMAGE] Aim: 1. To find out the beach material is moved by long shore drift 2. To work out a sort of defence mechanism used in porlock bay to stop the flooding in the marshes. Evidence of long shore drift: · Without long shore

• ## How Thickness and Length Affect the Resistance of a Wire

1497 Words  | 6 Pages

How Thickness and Length Affect the Resistance of a Wire I plan to investigate how the length and thickness of a wire affects the resistance. I plan to do this by keeping the voltage the same by using a variable resistor and measure the current when varied lengths and thicknesses of wire is in a circuit ===================================================================== Variables ========= There are a few factors that can affect the resistance. These are; * Temperature

• ## Investigating the Relationship Between the Length and Resistance of a Wire

681 Words  | 3 Pages

Investigating the Relationship Between the Length and Resistance of a Wire I am going to investigate to see if the change in the length of a wire will affect the size of a current My prediction ============= I predict that the longer the wire is the higher the resistance This is because there are free moving electrons being resisted by the atoms in the wire, which is converting electric energy to heat energy. So if the wire is longer there’ll be more electrons to collide with therefor

• ## Investigating How the Length of a Wire Affects Its Resistance

1181 Words  | 5 Pages

Investigating How the Length of a Wire Affects Its Resistance Planning: Risk Assessment: * I will handle the power supply carefully. * I am going to only use a maximum voltage of 2 volts. * I will be careful when handling the mains equipment. * I will make sure I have a clear space to work in and nothing on the floor around me. In this investigation, I will set up a simple circuit to be able to read the voltage and current when the length of wire changes, so I then can work

• ## The relationship between the length and the period of motion of a pendulum

1085 Words  | 5 Pages

Introduction: I chose to investigate this topic out of pure curiosity to see how the length of a pendulum affects its period of motion. A pendulum is a suspended point of mass, hung from a fixed point on an inextensible cord. When it is pulled and released from one side of its equilibrium, at x°, the pendulum swings back and forth on a vertical plane under the influence of gravity (La Né Powers, 2006). The motion is periodic and oscillatory; I am determining the oscillation or otherwise known as
