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 286 nm thick?

= ________ nm (incorrect answers: 380 nm, 380.38 nm)

B) To what color does this correspond?

(Red, Blue, Green, Orange) (incorrect answer: blue)

C) What wavelength (in air) of visible light is most strongly reflected from a point on a soap bubble where its wall is 342 nm thick?

= ________ nm

D) To what color does this correspond?

(Red, Blue, Green, Orange)
