Solution

The correct option is A
Voilet

Violet color deviates the most. This is because Violet has the least velocity in the spectrum and therefore undergoes maximum refraction. Red deviates the least as it has the highest velocity.

A ray of light gets dispersed into visible spectrum (VIBGYOR), when it is passed through a prism. Which color wavelength deviates the most?

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.

A ray of white light is passed through a glass prism and spectrum is obtained on a screen.

(a) Name the seven colours of the spectrum in order.

(b) Do the colours have the same width in the spectrum ?

Q. When white light passes through a thin glass prism, one gets spectrum on the other side of the prism. In the emergent beam, the ray which is deviating least is :
