Vedclass · Answer

(D) When light travels from one medium to another, the frequency of the light remains constant because it depends on the source of the light. However, the velocity $(v)$ and wavelength $(\lambda)$ of the light change according to the relation $v = f \lambda$, where $f$ is the frequency. Since the refractive index $(n)$ of the medium changes, the velocity changes as $v = c/n$, which subsequently causes the wavelength to change to maintain the constant frequency. Therefore, only wavelength and velocity change.

When light travels from one medium to another with a different refractive index, which of the following will change?

Light of wavelength $300 \ nm$ in medium $A$ enters into medium $B$ through a plane surface. If the frequency of light is $5 \times 10^{14} \ Hz$ and the ratio of speed in medium $A$ to that in medium $B$ is $\frac{4}{5}$,the absolute refractive index of medium $B$ is:

For a colour of light,the wavelength in air is $6000 \ \mathring A$ and in water,the wavelength is $4500 \ \mathring A$. Then the speed of light in water will be:
