Thin-Film Interference
Not what you're looking for?
We have not covered in class yet and the book does not offer much help. Is it asking for the value (m)? If so how is that determined? Thanks.
Light of wavelength 616 nm (in vacuum) is incident perpendicularly on a soap film (assume n = 1.36) suspended in the air. What are the two smallest nonzero film thicknesses (in nm) for which the reflected light undergoes constructive interference?
(a) ___nm (smallest thickness)
(b) ___nm (next smallest thickness)
