Its velocity increases

Vedclass · Answer

(A) When light travels from a denser medium (refractive index $\mu_1$) to a rarer medium (refractive index $\mu_2$),where $\mu_2 Since the refractive index $\mu$ decreases,the velocity $v$ of the light beam increases.The frequency of light depends only on the source and remains constant during refraction.The wavelength $\lambda$ is given by $\lambda = \frac{v}{f}$. Since $v$ increases and $f$ is constant,the wavelength $\lambda$ also increases.Therefore,the correct statement is that its velocity increases.

$A$ monochromatic beam of light passes from a denser medium into a rarer medium. As a result,
