Question

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.What visible wavelengths of light are strongly reflected from a 386-nm-thick soap bubble? What color would such a soap bubble appear to be? Hint: Think about the reflection phase shifts at both boundaries.

Step 1

Given: Refractive index of water (n) = 1.33 Thickness of soap bubble (d) = 386 nm Using the formula for constructive interference in thin films: λ1 = 2n*d / (M + 1), where M = 1 Substitute the values: λ1 = 2 * 1.33 * 386 / (1 + 1) λ1 = 684.5 nm Show more…
