Question

Monochromatic light of wavelength λ₁ travelling in a medium of refractive index μ₁ enters a denser medium of refractive index μ₂. The wavelength in the second medium is(a) $\lambda_{1}(\frac{\mu_{1}}{\mu_{2}})$(b) $\lambda_{1}(\frac{\mu_{2}}{\mu_{1}})$(c) $\lambda_{1}\frac{(\mu_{2}-\mu_{1})}{\mu_{2}}$(d) $\lambda_{1}\frac{(\mu_{2}-\mu_{1})}{\mu_{1}}$

Answer 1

Hey

(a) $\lambda_{1}(\frac{\mu_{1}}{\mu_{2}})$(b) $\lambda_{1}(\frac{\mu_{2}}{\mu_{1}})$(c) $\lambda_{1}\frac{(\mu_{2}-\mu_{1})}{\mu_{2}}$(d) $\lambda_{1}\frac{(\mu_{2}-\mu_{1})}{\mu_{1}}$

B correct
