Question

At normal incidence the reflected rays which are in phase with each other are....

Please show all work, thanks!

At normal incidence the reflected rays which are in phase with each other are... light of wavelength lambda is incident on two thin films that are in contact and surrounded by air. The top laye is lambda/4 thick and has n = 1.33 and the bottom layer is lambda/2 has n = 1.50. At normal incidence, the reflected rays which are in phase with each other are 1 and 2 1 and 3 2 and 3 1, 2 and 3 none of these

Explanation / Answer

at normal incidence,the reflected ray also reflects normal to the surface

Applw the law of reflection

angle of incidence = angle of reflection

i = r

at normal incidence i = 0 degrees

and r = 0 degrees

So the answer is e) none of these
