Question

) The refractive index of glass, when a ray of light travels from air to glass is 1.5. Calculate the refractive index when light travels from glass to air. hi​

Answer 1

Answer:

0.67

Explanation:

= 1/1.5 = 2/3 = 0.66.... = 0.67(approx.)

DO THE RECIPROCAL OF THE GIVEN REFRACTIVE INDEX.

Answer 2

Given: refractive index of glass when light travels from air to glass = 1.5

To find: refractive index when light travels from glass to air

Solution:

Refractive index when light travels from glass to air = 1/refractive when light travels from air to glass.

Therefore , refractive index = 1/1.5 = 0.67

Therefore, the refractive index when light travels from glass to air is 0.67

• The Refractive index is the dimensionless number that represents how fast the light travels through that material. It is the ratio of the speed of light in that material to the speed of light in air.
• refractive index, n = c/v. Where c is the speed of light in air and v is the speed of light in that medium.
• The vacuum has a refractive index of 1.
