PhysicsEasysingle choice

When a ray is refracted from one medium into another medium, the wavelength changes from $6000 Å$ to $4000 Å$ . The critical angle for a ray from second medium will be

Options:

Answer:

Solution:

$\sin C = \frac{μ_{R}}{μ_{D}} = \frac{λ_{D}}{λ_{R}} = \frac{4000}{6000} = \frac{2}{3}$
