Soap bubbles can display impressive colors, which are the result of the enhanced reflection of light of particular wavelengths from the bubbles\' walls. For a soap solution with index of refraction of 1.09, find the minimum wall thickness that will enhance the reflection of light of wavelength 715 nm in air.
