Deviation Produced by a Triangular Prism

For obtaining a pure spectrum, the slit in front of the source needs to be as narrow as possible.

What are the conditions to get pure spectrum?

 A pure spectrum, on the other hand, is one in which different colours are overlapped.

Differentiate between pure and impure spectrum.

The correct arrangement of colors in the descending order of their wavelength

When a ray of light is passed through a hollow glass prism, it does not give spectrum.

When white light is incident on the surface of an equiangular triangular prism, which colour is deviated the most?

The prism should be placed in the position of _____ deviation to obtain a pure spectrum on a screen.

The deviation produced by a prism depends on the material, angle of incidence and angle of _____.

When white light is dispersed by a prism, compared with blue light, the red light is

If a ray of light enters glass prism (as shown in figure) of refractive index $1.5$, then the speed of light inside the prism will be
