Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of electromagnetic wave has slightly more energy than an X ray?
A
gamma wave
B
infra red wave
C
microwave
D
ultra violet wave
E
radio wave
Explanation: 

Detailed explanation-1: -Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.

Detailed explanation-2: -In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.

Detailed explanation-3: -Gamma-ray photons have the highest energy in the EMR spectrum and their waves have the shortest wavelength. Scientists measure the energy of photons in electron volts (eV). X-ray photons have energies in the range 100 eV to 100, 000 eV (or 100 keV). Gamma-ray photons generally have energies greater than 100 keV.

Detailed explanation-4: -The energy of a wave depends on its wavelength: the longer the wavelength, the lower the energy. Therefore, in the electromagnetic spectrum, gamma rays have the highest energy, and long radio waves the lowest.

Detailed explanation-5: -Recall that radio waves have the longest wavelength of any electromagnetic wave. Next, it’s microwaves, then infrared, then visible light, which contains all the colors we can see, then we have ultraviolet, and then X-rays. Finally, the type of wave with the shortest wavelength is .
