Radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X rays, and gamma rays are forms of radiant energy that make up the electromagnetic spectrum. Each portion of the electromagnetic spectrum has waves that vary in frequency and wavelength, but all can be used by people. Radio waves can be used to carry music and voices for great distances through air, X rays can be used for diagnostic work in medicine, and infrared radiation can be used for heating and drying.
What appears to be the difference in the waves when moving from radio waves to X rays in the electromagnetic spectrum?
A . decreased wavelength
B . decreased energy
C . decreased frequency
D . increased wavelength and energy
E . increased wavelength and frequency
Answer: A
