light of a wavelength 600 nm shines on a soap bubble film. For what soap film thickness will destructive interference occur

The minimum thickness of the soap bubble for destructive interference to occur is 225.56 nm.

Explanation:

Given;

wavelength of light, λ = 600 nm

The minimum thickness of the soap bubble for destructive interference to occur is given by;

where;

n is refractive index of soap film = 1.33

Therefore, the minimum thickness of the soap bubble for destructive interference to occur is 225.56 nm.
