A soap bubble with walls 402 nm thick floats in air. If this bubble is illuminated perpendicularly with sunlight, what wavelength of visible light will be absent in the reflected light? Assume that the index of refraction of the soap film is 1.33.

A soap bubble with walls $401 \mathrm{~nm}$ thick floats in air. If this bubble is illuminated with sunlight (wavelengths from $400 \mathrm{~nm}$ to $700 \mathrm{~nm}$ ), what wavelength will be absent in the reflected light? Assume that the index of refraction of the soap film is $1.33$.
The walls of a soap bubble have about the same index of refraction as that of plain water, $n$ = 1.33. There is air both inside and outside the bubble. (a) What wavelength (in air) of visible light is most strongly reflected from a point on a soap bubble where its wall is 290 nm thick? To what color does this correspond (see Fig. 32.4 and Table 32.1)? (b) Repeat part (a) for a wall thickness of 340 nm.
