The speed of light with the rise in the temperature of the medium
|
|
Increases
|
|
|
Decreases
|
|
|
Remains unaltered
|
|
|
Drops sharply
|
Explanation:
Detailed explanation-1: -The speed of light is a universal constant and therefore, does not depend on temperature. So, with the rise in temperature, the speed of light remains unaffected and unaltered.
Detailed explanation-2: -The speed of light is maximum in a vacuum. Vacuum is the least dense medium with no obstruction to the path of light. Its refractive index is equal to unity, hence, the speed of light is maximum in a vacuum.
Detailed explanation-3: -Light and temperature The wavelength of the light emitted often depends very closely on the temperature of the object that is emitting it.
