Minimum thickness of the film that will achieve the result

Reference no: EM13673246

A sheet of glass having an index of refraction of 1.40 is to be coated with a film of material having an index of refraction of1.55 in order that green light by a wavelength of 525 nm (in air)will be preferentially transmitted via constructive interference

1) What is the minimum thickness of the film that will achieve the result?

2) Why are other parts of the visible spectrum not also preferentially transmitted?

3) Will the transmission of any colors be brusquely reduced? If so what colors?
