surface is perfectly elastic there is no change in kinetic energy. This also been proven before by measuring the two variables before and after reflection. In order to change the speed of light‚ either the frequency or the wavelength has to change. The results have shown equivalent values for both of the variables. Thus indicating and proving that the speed of light stays the same after being reflected off a surface. Refraction Refraction is the bending of light through a substance. Different substances

You will compare your actual force with the theoretical force and provide a computer generated data table that calculates the theoretical values. You will graph your actual and theoretical values and provide a complete table of % errors for your results. Your paragraph will discuss all the questions below in depth. Procedure and Data: 1. Tie the two pieces of string to the scales. 2. Hang a 1.00kg mass from the center of the string and move the clamps together such that the total angle between

6. Applications * Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water‚ but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing

A2 History Coursework Using these four passages and your own knowledge‚ asses the view that international diplomacy failed to achieve stability in Europe from 1919 to 1930. According to most of the interpretations‚ international diplomacy wasn’t the reason to why there was stability in Europe between 1919 to 1930. After the First World War many countries were unstable and economically drained. However the League of Nations and the Treaty of Versailles were put in place to make sure that another war

Objectives: • To be able to explain how the photoelectric effect experiment works and why a photon model of light is necessary to explain the results. • To study the effect of intensity of light on photoelectric experiment. • To estimate the Planck’s constant‚ h through the simulation. • To be determine how to calculate the wavelength of light‚ the work function of the metal‚ or the stopping potential‚ if given the other two. Beginning with the plate made of sodium. Keep all the parameters

I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties
