Electromagnetic waves travel with the velocity of a.3000 kilometre per secondb. 3 lakh kilometres per secondc.3 kilometres per secondd.NONE​

Answer»

hii I think that it HELPS youExplanation:electromagnetic wave has a FREQUENCY and a wavelength ASSOCIATED with it and travels at the speed of LIGHT, or c. The relationship among these wave characteristics can be described by vW = fλ, where vW is the propagation speed of the wave, f is the frequency, and λ is the wavelength. Here vW = c, so that for all electromagnetic waves, c = fλ.Thus, for all electromagnetic waves, the GREATER the frequency, the smaller the wavelength.
