Light with wavelength 530 nm in air (n = 1) passes through a soap bubble (n = 1.33), where its wavelength becomes ≈ 400 nm.
A What is the phase difference between a light wave reflected off the surface of the bubble and one that passes into it before being reflected?
B The thickness of the bubble is 100 nm. Does this lead to constructive or destructive interference?
C What would happen for a soap film covering a glass surface (n = 1.5)? How does this affect the difference in phase?
Give in depth explanation.
