The wavelength of light emitted by a particular laser is 477 nm. this laser light illuminates two slits that are 54.0 µm apart, and a screen is 1.40 m from the slits. what is the angular separation between the n = 2 and n = ? 2 maxima?

The angular separation is 2.024°.

Explanation:

Given that,

Wavelength = 477 nm

Distance of two slits d= 54.0 μm

Distance from screen = 1.40 m

We need to calculate the angular separation

Using formula of angular separation

Where, d = distance

= wavelength

Put the value into the formula

The angular separation is

Put the value into the formula

Hence, The angular separation is 2.024°.
