Problem 2CQ

The speed of light in glass is less than c. Why is this not a violation of the second postulate of relativity?

Step-by-Step Solution:

Solution 2 CQ:

Step 1 of 1:-

As the speed of light is less than “c” in glass medium, why it’s not a violation of the 2nd postulate of special relativity we have to explain here.

The 2nd postulate clearly tells that, the vacuum speed of light is constant for all inertial observers. So, the less speed in glass medium does not violate the postulate.

The speed of light in different mediums is related with the refractive index of the medium and it is consistent with all the laws of physics.
