Question

what do you understand by interface in light chapter ?​

Answer 1

Answer:

hi here is ur answer

Explanation:

An interface is a boundary shared by two media. To a wave entering a medium with a slower wave speed,the interface is more like a fixed end than a free end.

hope it help u

Answer 2

Answer:

A illustrates what happens when electromagnetic radiation crosses a smooth interface into a dielectric medium that has a higher refractive index (nt>ni). We see two phenomena: reflection and refraction (a specific type of transmission). The angle of reflection, θr, equals the angle of incidence, θi, where each is defined with respect to the surface normal. The angle of refraction, θt, (t for transmitted) is described by Snell’s law (of Refraction):
