Coherent light of wavelength 519 nm passes through two slits. in the resulting interference pattern on a screen 4.6 m away, adjacent bright fringes are 4.0 mm apart. what is the angular separation (in radians) between the central maximum and the first-order maximum?

angular separation = 0.04981868 deg

Explanation:

Given data

wavelength λ = 519 nm

bright fringes y = 4.0 mm

interference D = 4.6 m

to find out

angular separation

solution

we will find angular seperation between central maximum and the first order maximum that is

angular separation = bright fringes / interference

put here all value

angular separation = 8.695 × 10^(-4) rad

angular separation = 0.04981868 deg
