Randall D. Knight β Superposition: Problem Problem_66
A soap bubble is essentially a very thin film of water ($n = 1.33$) surrounded by air. The colors that you see in soap bubbles are produced by interference. a. Derive an expression for the wavelengths $\lambda_C$ for which constructive interference causes a strong reflection from a soap bubble of thickness $d$. Hint: Think about the reflection phase shifts at both boundaries. b. What visible wavelengths of light are strongly reflected from a 390-nm-thick soap bubble? What color would such a soap bubble appear to be?
