To solve this problem we will apply the concepts related to the double slit-experiment. For which we will relate the distance between the Slits and the Diffraction Angle with the order of the bright fringe and the wavelength, this is mathematically given as,
Here,
d = Distance between Slits
m = Order of the fringes
= Wavelength
=
Rearranging to find the angle,
Therefore the angle that the fourth order bright fringe occur for this specific wavelenth of light occur is 32.19°
