Question

Match the Columns:

Hint:

The refractive index of a material measures how much light bends when entering it. The refractive index of water is 1.33, meaning light slows down and bends when passing through water.

Answer 1

Step 1: Understanding the refractive index
The refractive index (\(n\)) of a medium is the ratio of the speed of light in a vacuum to the speed of light in that medium.
Step 2: Identifying the correct value for water
- The standard refractive index of water is 1.33. - This value is determined experimentally and used in optics calculations.
Step 3: Matching with given options
- 1.31 is close but corresponds to some organic liquids. - 1.36 is typical for some oils and other transparent liquids. - 1.33 is the correct refractive index of water. Thus, the correct match is Refractive index of water = (c) 1.33.
