Since, from the formula λ =(c/v) hence, (λ a/λ g)=(ca/cg)=μ =μ :1.

Q. Monochromatic light is refracted from air into the glass of refractive index $μ$ . The ratio of the wavelength of incident and refracted waves is:

1:1

$μ : 1$

1: $μ^{2}$

$1 : μ$

Since, from the formula $λ = \frac{c}{v}$ hence, $\frac{λ _{a}}{λ _{g}} = \frac{c _{a}}{c _{g}} = μ = μ : 1.$
