Question

a) Let's suppose that, wlien lielut is incident on an interluce between two material the
the refructed ray depends on the wavelength, but the angle of reflected ray does not Why
should this be? Explain tur answer with the heip of diagram. (5 points)​

Answer 1

Answer:

pls follow me

Explanation:

(i) The ratio of the sine of angle of incidence 'i' to the sine of angle of refraction 'r' is constant for the given pair of media. This constant is called the refractive index.

μ=

sinr

sini

(ii) It occurs due to change in speed of light as it enters from one medium to other medium having different optical density.

(iii) When a ray of light is incident normally on the surface of second medium, it
