Monochromatic light shines perpendicularly on a soap film

Reference no: EM13654191

When monochromatic light shines perpendicularly on a soap film(n = 1.33) with air on each side, the second smallestnonzero film thickness for which destructive interference ofreflected light is observed is 386 nm. What is the vacuum wavelength of thelight in nm?
