A soap bubble with n=1.33 is illuminated by white light and produces constructive interference for a wavelength of 410 nm. The bubble is in air.

a. Sketch the situation indicating where the light is reflected and what the indices of refraction are at each reflection.

b. Is the reflected wave inverted at the air-to-bubble interface? Explain.

c. Is the reflected wave inverted at the bubble-to-air interface? Explain.

d. What is the minimum thickness of the bubble to produce constructive interference at this wavelength?

e. What wavelength destructively interferes at this bubble thickness?

A soap bubble is essentially a very thin film of water (nn = 1.33) surrounded by air. The colors that you see in soap bubbles are produced by interference. What visible wavelengths of light are strongly reflected from a 388-nmnm-thick soap bubble? Hint: Think about the reflection phase shifts at both boundaries. What color would such a soap bubble appear to be?
