Question

What is dispersion of light ? Draw necessary diagram.​

Answer 1

Answer:

Draw a diagram to show the dispersion of white light by a glass prism. When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as dispersion.

Answer 2

★ Dispersion of Light ★

• The dispersion of light is a process where white light disperse into 7 colours from a glass prism.
• The name of seven colours are :- red, orange, yellow, Green, Blue, Indigo, Violet.

★ ADDITIONAL INFORMATION ★

• The ratio of the speed of light in medium 1 to medium 2.
• The image formed by a concave lens , is always virtual, erect and diminished.
• The distance between the pole and focus of the mirror is known as focal length (For spherical mirror) and the distance between the optical centre and the principal focus is known as focal length (For lens).
• The line joining the pole and focus of the mirror is known as principal axis (For is medical mirrors).
• The line join centre of curvature to the surfaces of lens is known as principal axis (For lens)
