Rutvi Patel and Sandhya‚ determining the wavelength of light from a laser using a double – slit slide. The laser was shone through the double – slit such that it projected interference pattern onto the paper screen. The experiment will be repeated three times varying the distance between the slit and the screen to understand the effective relationships. The expected wavelength of the laser light is 6.5 X 10-7‚ however‚ the value found of the wavelength is 7.56 X 10-7 with an error of 16.3%. The

In the displacement – distance graph as shown above‚ amplitude is represented by the symbol of a and wavelength is represented by the symbol of λ 6. Damping is occur when in an oscillating system when the system loses ( gain / loses) energy to surrounding in the form of heat ( heat / chemical ) energy. 7. The force responsible for damping is called dissipative

Nietkalieva Dinara IS113k Lab 1: Radio and Light Waves Virtual Lab 1) How is the radiating electric field (or electromagnetic signal) produced when radio stations broadcast? Include a description of what is producing the signal as well as the reasoning behind how this could produce a signal. We know that electromagnetic radiation is produced by accelerating charges. In the radio transmitter‚ electrons oscillate up and down and are thus accelerating. An electron will exert a force on another

EXPERIMENT 8 To Determine the Wavelength of Sodium Light using Newton’s Rings Please read additional instructions on the bench for setting up the PC and camera for this experiment Introduction Newton’s rings are interference fringes of equal thickness which are produced in the air film between a convex surface and an optical flat. It is interesting to note that these interference fringes‚ which demonstrate the wave nature of light‚ should be credited to Newton who was the chief proponent of the

Radio waves for Communication Radio waves are electromagnetic waves with wavelengths larger than the infrared light. Like all other electromagnetic waves‚ they travel at the speed of light. The wavelengths can vary from the size of a football field to the size of a football. They can be produced naturally by large stars and by lightning. Man-made radio waves are used for transmitting signals and currents. Specific Properties of Radio Frequency (RF) Current Radio frequency is the frequency of radio

A tsunami is made up of a series of travelling ocean waves of extremely long wavelength. 2. There are two types of tsunami that affect the New Zealand coastline: * Far-field tsunami - generated from fault lines or submarine landslides‚ usually along the coastline of North America or South America. * Near-field tsunami - generated

EXPERIMENT: 1 Object: To find the wavelength of Sodium light by Newton’s ring. Apparatus required: A Plano convex lens of large radius of curvature‚ optical arrangement for Newton’s rings‚ plane glass plate; sodium lamp and traveling microscope. Formula used: The wavelength of light is given by the formula λ =D n2+p –Dn2 / 4pR Where D n+p = diameter of (n+p)th ring Dn = diameter of n th ring‚ P = an integer number‚ R = radius of curvature of the curved face of the Plano- convex lens.

CHAPTER 1 Graphs are used to study the relationship between 2 things so you can see what the relationship is. Unrelated: 2 items that are not associated. Ex. Hair color is unrelated to shoe size Directly related/proportional: 2 items that are associated such that when one item increases‚ the other increases. The graph of 2 directly related items extends from lower left to upper right. Ex. Clothing size is directly related to one’s weight. Related/ proportional: Is a relationship but can’t
