Explain the cause of dispersion of white light through a prism.

What is the cause of dispersion of white light through a glass prism Draw a ray diagram to show the path of light when two identical glass prisms are arranged together in inverted position with respect to each other and narrow beam of white light is allowed to fall obliquely on one of the faces of the prisms.

Explain the phenomenon of dispersion of white light through a glass prism, using suitable ray diagram.

For refractin of light through a prism

Define the term dispersion of light.

Which of the following diagrams shows correctly the dispersion of white light by a prism ?

Explain the refraction of light through a triangular glass prism using a labelled ray diagram. Hence define the angle of diviation.

In refraction of light through a prism the light ray:

The difference between angle of minimum deviation of violet and red rays in the spectrum of white light from a prism is 2^(@) . If angle of minimum deviation of mean ray is 48^(@) , the dispersive power of material of the prism is

Draw a neat and labelled diagram, when a ray of white light passes through an equilateral prism.

The band of seven colours obtained on a screen when white light passes through a prism is called spectrum. ____
