If the speed of light in air is and the speed of light in water is reduced by a factor of when compared with that of the speed of light in air. Find out the speed of light in water?
Step 1. Given data:
Speed of light in air =
Refractive index =
Let = Speed of light in any other medium.
Step 2. Formula used:
Refractive index = Speed of light in air Speed of light in water.
So, Speed of light in water = Speed of light in airRefractive index
Step 3. Calculation:
Hence, the speed of light in water=
Thus, the speed of light in water will be
