Vedclass · Answer

(B) Thermal radiation consists of electromagnetic waves,which behave similarly to light. When electromagnetic radiation travels from one medium to another,its speed and wavelength change due to the change in the refractive index of the medium. However,the frequency of the radiation is a property of the source and remains constant regardless of the medium through which it travels. Therefore,the statement that frequency changes is incorrect.
