The inside surface of a glass window (n= 1.5) is coated with a material of n= 1.38. If the surface reflects 570 nm of light back into the room. What is its thickness?
Is the answer : 2d = lambda/n ?? this should be constructive interference. am I wrong?
Homework Answers
Yes constructive interference
path difference delta x = 2d ( n ) n = 1.38
for constructive interference delta x = lambda
there fore
2d = lambda/1.38
d = 206.52 nm ( answer )
