A red He-Ne laser and a green Kr-Ar laser shine through a double slit, where the spacing between the slits is 50.0 um. The red laser has a wavelength of 632.8 nm while the green laser has a wavelength of 514.5 nm The distance between the central bright spot and the first red fringe is 3.1 cm . The small angle approximation can be assumed in this question. Recall u = 10-6 n = 2 n = 1 n= 1 Central bright spot • Part A What is the distance between the screen and the double slit? D= Submit Reguest Answer Part B How far (in centimeters) from each side of the first red fringe is a green fringe located?

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.
