light travels through air, hits a film (n=1.3) and underneath that film is glass (n=1.5). What thickness of film would result in destructive interference
The lights wavelength is 500nm.
n = c/v
V = F*λ
The Attempt at a Solution
I drew some diagrams, and my attempt is also on the diagram,
the diagram is attached
Also, I was wondering what an increase in n signifies?
is it increase in density?
and also, I believe a wave flips when it reflects off something with higher n? (fixed boundary) and moves as is through something with less n? (free boundary)
could someone confirm this please?
