Question

When monochromatic light shines perpendicularly on a soap film (n = 1.33) with air on each side, the second smallest nonzero film thickness for which destructive interference of reflected light is observed is 330 nm. What is the vacuum wavelength of the light in nm?
I keep getting 438.9 but it says its not right When monochromatic light shines perpendicularly on a soap film (n = 1.33) with air on each side, the second smallest nonzero film thickness for which destructive interference of reflected light is observed is 330 nm.

Explanation / Answer

in this case we use
    ?film = ?vacuum/ n
    ?vacuum = ?filmn
                 = ......... nm
