An x- ray is part of the electromagnetic spectrum. Compared to photons of visible light, an x-ray has?

Explanation:

X-rays are almost same as the visible light as they both electromagnetic waves with same speed. However, the only difference the energy level of photons of X- rays are higher than those of the visible light. This is because the frequency of the X-rays are higher.

E=

h= plank's constant and \nu is the frequency of the wave. So, higher the  frequency higher will be the energy of the wave.

Explanation:

X-rays are the electromagnetic waves whose photons are of higher energy and short wavelength that ranges beyond the visible region for the human-eyes.

The visible light lies between the wavelength of 4000 to 7000 .

The x-ray photons are the result of highly excited electron from its ground state than the electron releasing visible light photons.

The smaller atoms, in which the electron orbitals are separated by relatively low jumps in energy, are less likely to absorb X-ray photons.
