Answer:
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.
Dominoes does because when you hit one, it knocks over the next one, and so on, so forth. The same type of pattern happens in a wave.
