White light splits into different colors through a prism and this phenomenon is known as dispersion of light.
Statement 1: When white light ray passes through a prism it disperses into seven different colours, and this phenomenon is called dispersion.
Statement 2: Refraction depends upon the wavelength of light and since different colours have different wavelengths, they are refracted at different angles and so they are split into the colour spectrum.
An optical instrument which can split white light into seven different colors is known as
The splitting of white light into several colors on passing through a glass prism is due to
