Interference Patterns
This report will be performed by a group of 3 students viz. Harleen Kaur, 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 difference in values is due to human and random errors.

INTRODUCTION An English scientist, Thomas Young, first performed the double slit experiment in the early 1800s. In this experiment, light was allowed to diffract through slits, which produced fringes, or wave-like interference patterns on an opposing screen. In the basic version of the experiment, a coherent light source, e.g. laser beam, illuminates a thin double slit plate, and the light passing through the slits is observed on a screen behind the plate. The wave nature of light causes the light waves passing through the two slits to
