Question

When a light ray is refracted from one
medium into another, the wavelength
changes from 4500 4° to 30004". The
critial angle for a ray from second
medium to first medium is
​

Answer 1

Answer:

λ1 = 450nm , λ2 = 300nm Refractive Index, 1μ2 = v1v2 = νλ1νλ2 = 450300 = 32 2 μ1 = 23 , again we know θc (critical angle) = sin-1(2μ1) θc .
