Suppose the distance between the slits in a double-slit experiment is `2.00 xx 10^(–5) m`. A beam of light with a wavelength of 750 nm is incident on the slits. What is the angular separation between the central maximum and the adjacent maximum?

Options

A. `5.00 xx 10^(-2)` rad
B. `3.75 xx 10^(-2)` rad
C. `4.50 xx 10^(-2)` rad
D. `2.50 xx 10^(-2)` rad

Answer

B

Explanation

`tan theta = theta = (lambda)/(d) = (750 xx 10^(-9))/(2 xx 10^(-5)) = 3.75 xx 10^(-2) rad`.
