Explanation:
Statements :
1) Rayleigh's law of scattering can be applied only when the size of the scatterer is very much less than the wavelength of light.
This statement is correct.
2) Mass density of an optically denser medium may be less than that of an optically rarer medium.
This statement is correct.
3) The apparent flattening of the sun at sunset and sunrise is due to the refraction of light.
This statement is correct.
4) Refractive index of a medium is the same for all colors of light.
This statement is wrong.
Correct statement: Refractive index is different for different colors.
Reason :
Because every color has a particular wavelength, differing wavelengths induce differences in the velocity of colors when they move from one medium to another through a glass prism. Additionally, as the refractive index varies with light wavelength, different velocities result from different wavelengths having varying refractive indices.
Each wave has a certain color depending on its wavelength. Utilize the light spectrum to comprehend these hues. All colors move at the same speed in a vacuum or c. Their velocities change as they go from vacuum into another medium. As a result, the colors have various refractive indices.
