Question

Why does speed of light increases with increase in temperature?
Please answer, I will mark you as brainlist.

Answer 1

Answer:

because speed is directly proportional to temperature

Answer 2

Speed of light increases with increase in temperature.  

Step-by_step explanation:

1. speed of light increases with increase in temperature.  
2. In vacuum speed of light does not depend upon anything and it does not change with temperature .
3. speed of light increases with increase in temperature in a medium. when light passes through a optical medium and temperature rises then the optical medium expands.  As the medium expands, the refractive index of the medium decreases and the speed of light increases in the medium.
