They travel with the same speed in all media.

Vedclass · Answer

(B) Electromagnetic waves are transverse waves and do not require a material medium for propagation.Electromagnetic waves travel at the speed of light $(c \approx 3 	imes 10^8 \ m/s)$ in a vacuum.Accelerating electric charges are the source of electromagnetic waves.The speed of electromagnetic waves depends on the medium through which they travel,given by the formula $v = c/n$,where $n$ is the refractive index of the medium. Therefore,they do not travel at the same speed in all media.Thus,the statement that they travel with the same speed in all media is incorrect.
