Electromagnetic Waves & Wave Energy

Question

X-rays are electromagnetic waves that can penetrate skin, but not bone. In hospitals, X-rays are used to produce images of bones. How do X-rays compare to visible light?

 A. 

X-rays have a higher frequency and carry more energy than visible light.

 B. 

Visible light has a higher frequency and carries less energy than X-rays.

 C. 

X-rays have a higher frequency and carry less energy than visible light.

 D. 

Visible light has a higher frequency and carries more energy than X-rays.

Answer 1

The order of the spectrum going from low frequency to high frequency is

Radio - Microwaves - Infra Red - Visible Light -Ultra Violet- X Rays - Gamma Rays

Also the higher the frequency the higher the energy (E=hf)

Therefore X-Rays are a higher frequency and have a higher energy
