Question

A ray of light passes from air to water in next case from air to diamond in whic does the ray of light bend more​

Answer 1

A ray of light passes from air to water and in the next case from air to diamond. The ray of light will bend more in the case of a diamond. The reason is :

• The refractive index of water is 1.36 and the refractive index of diamond is 2.42.

• As the refractive index of diamond is greater than water, therefore the ray of light bends more in a diamond.

• If the angle of incidence if 40°, the light bends with an angle of 16° in diamond and with an angle of 29° in water.

• The bending of light also depends on the speed of light. The speed of light is slow in diamond in comparison to water, therefore it bends more in a diamond.
