If the refractive indices of flint glass for red, yellow and violet light are 1.612, 1.620 and 1.632 respectively, then find the dispersive power of flint glass.
1 0.033
2 0.011
3 0.055
4 0.022
Explanation:
A: Given, \(\mu_{\mathrm{R}}=1.612, \mu_{\mathrm{Y}}=1.620, \mu_{\mathrm{V}}=1.632\)
Dispersive power \((\omega)=\frac{\mu_{\mathrm{V}}-\mu_{\mathrm{R}}}{\mu_{\mathrm{Y}}-1}\)
\(\omega=\frac{(1.632-1.612)}{(1.620-1)}=\frac{0.02}{0.62}=0.033\)

The sun appears orange red at sunrise and sunset. This is because of
1 scattering of light
2 reflection of light
3 refraction of light
4 total internal reflection
Explanation:
A: Scattering of lightWhen light passes from one medium to another medium, then a part of light is absorbed by particles of the medium, preceded by its subsequent radiation in a particular direction. This phenomenon is known as scattering of light.
