Q. Fill in the blanks:

The refractive index depends upon the ________ of propagation of light in different media.

Statement 1: When white light ray passes through a prism it disperses into seven different colours this phenomenon is called dispersion.

Statement 2: Refraction depends on upon the wavelength of light and since different colours have different wavelengths hence are refracted at the different angle and so they are split into the colour spectrum.
