1.	A beam of monochromatic light is refracted from vacuum into a medium of refraction index 1.5. the wavelength of refracted light will be.(a) Depend on intensity of refracted light(b) Same(c) smaller(d) larger
Answer» (c) smaller Explanation: velocity of light decreases in a medium. Hence λ decrease in a medium (v ∝ λ).

Answer»

(c) smaller

Explanation:

velocity of light decreases in a medium. Hence λ decrease in a medium (v ∝ λ).
