Light with wavelength 530 nm in air (n = 1) passes through asoap bubble (n = 1.33), where its wavelength becomes ≈ 400 nm.
A What is the phase difference between a light wave reflectedoff the surface of the bubble and one that passes into it beforebeing reflected?
B The thickness of the bubble is 100 nm. Does this lead toconstructive 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.
