Monochromatic light shines perpendicularly on a soap film

Reference no: EM13663032

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 422 nm. What is the vacuum wavelength of the light in nm?
