Q. State the cause of dispersion of white light by glass prism. How did Newton, using two identical glass prisms show that white light is made of seven colours? Draw a ray diagram to show the path of a narrow beam of white light, through combination of two identical prisms (where one of the prism is in an inverted position with respect to the other), when it is allowed to fall obliquely on one of the face of the first prism of the combination.

Q. A beam of white light passes through two inverted prisms as shown.
