Interference by Thin Films - Physics - eSaral

Hey, do you want to learn about the interference by thin films? If so. Then you are at the right place. Interference by Thin Films The interference caused by thin films is due to the interference between the waves reflected from the upper and lower surfaces. These two reflected coherent waves are obtained from the same incident wave by division of amplitude. A film of thickness t and refractive index $\mu$ produces a path difference of $2 \mu \mathrm{cos} \mathrm {r}$ between the two reflected w...
