43. A photon of X-ray has energy of 1 keV. A photon of visible radiation has energy of 3 eV. In this context, which one of the following statements is not correct? A.The wavelength of X-ray photon is less than the wavelength of visible radiation photon. B.Both the photons have different energies. C.The speeds of both the photons in vacuum are different D.The frequency of X-ray photon is higher than the frequency of visible radiation photon.
Option C Solution: The speed of all the electromagnetic radiation are always same and equal to the numerical value 3 x 108 m/sec.
