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. `5.00xx10^(-2)` rad
B. `3.75xx10^(-2)` rad
C. `4.50xx10^(-2)`rad
D. `2.50xx10^(-2)`rad

Answer

B

Explanation

`tan theta ~=theta=(lamda)/d=(750xx10^(-9))/(2xx10^(-5))=3.75`
`xx10^(-2)` rad
