Diffraction and Interference of Light

Abstract
This objective of this science lab is to utilize the wavelike description of swooning to predict its properties. A laser unfounded was set up at iodin end of an optics track with two contrary twat attachments placed in front of it, and a fraction of graph paper at the other end to scan the peckers produced by the laser. The experiment was then repeated with yet oneness slit for the elucidateing to pass through. The resultant rays that were produced from the light hit the slits were then measured and recorded. With these it was able to be determined that light does indeed have wavelike properties.
Introduction
The purpose of this lab was to use the wavelike description of light to describe its properties. Although certain properties of light that cannot be seen with the naked eye or explained by ray optics, there are certain phenomena of light that can only be explained by a wave description. When describing the interference of light from a double slit, the equation used is
n?=tsin(A)
Where n is the rule, ? establishs the wavelength, t is the separation between the slits, and A is the angle.



To determine the sleek spot of the light, we use the facial expression
n?=tD/L
Where n is the order, ? represents the wavelength, t is the separation between the slits, D is the distance from the focus of the diffraction pattern to the center of the bright spot, and L is the distance from the slit to the screen. The second formula that was for a dark spot was
n?=dD/L
Where n, ?, D, L represent the same things as above, and d represents the slit width. The hypothesis of this lab will be that the laser will behave in a pattern that displays the wavelike phenomena associated with light. This experiment will benefactor us to perceive this phenomena as well as to assistance us understand it.

Apparatus
The materials that were used in this lab were lasers, optics track, slit attachments, screen attachments, clamps, and graph paper.


Procedure
For this experiment, a laser was positioned at one end of...If you want to get a full essay, order it on our website: Ordercustompaper.com
