Choose the INCORRECT statement concerning electromagnetic radiation.
A) Infrared light has a longer wavelength than ultraviolet light.
B) The greater the frequency of the electromagnetic radiation, the greater the energy of the radiation.
C) A photon with a wavelength of 5000 Angstroms has one-half as much energy as a photon with a wavelength of 2500 Angstroms.
D) The speed of ultraviolet light rays is faster than X-rays in a vacuum.
E) Electromagnetic radiation is energy transmission in which electric and magnetic fields are propagated as waves.

Question

Quizplus · Accepted Answer

The speed of all electromagnetic radiation is constant in a vacuum and does not vary based on wavelength or frequency. Therefore, ultraviolet light and X-rays would travel at the same speed in a vacuum.
