Hello Dheeraj,
Here, wavelength of light = 4500 angstroms (Given)
Width of slit = 2 * 10^-4 m (Given)
Required angle = 2 * theta ~ 2 * sin theta [For very small angles theta = sin theta]
Therefore, Required angle = 2 * Wavelength / Width
= (2 * 4500 * 10^-10) / (2 * 10^-4)
= 4500 * 10^-6
= 4.5 * 10^-3 radian (Answer)
