Vedclass · Answer

(D) The velocity of light in a vacuum is a universal constant given by $c = 2.9979 	imes 10^8 \ m/s$.Since $c$ is a constant in a vacuum,it does not change.If the velocity of light were to change,it would imply a change in the medium or a change in the fundamental constants of nature.However,the question asks what changes if the velocity of light in a vacuum changes,which is a hypothetical scenario.In reality,the velocity of light in a vacuum is invariant.Therefore,none of the listed quantities (frequency,wavelength,or amplitude) are responsible for changing the speed of light in a vacuum,as the speed of light is independent of these factors in a vacuum.

Which of the following quantities changes when the velocity of light in a vacuum changes?
