Question

24. A rainbow is formed when a ray of sunlight passes
through a spherical raindrop. Then the total angle through
which the ray deviates is (i and r denote the angles of
incidence and of the refraction respectively)

(a) 2i- +4i
(b) pi 2i - 41
(c) 2(i-r)
(d) 2( pi +i - 2r)
​

Answer 1

Answer:

a

Explanation:

Answer 2

Answer:

{ a }- 2i-+4i is your answer

as we know when a light ray passes through the sperical prism then the white light get diverge into 7 rainbow colours and hence we can see any thing
