What is the crest?
100
This is the only part of the electromagnetic spectrum that humans can see.
What is visible light?
100
These waves are used to examine broken bones.
What are X-rays?
100
The greater the frequency, the ___ energy a wave has.
What is more?
200
The distance between two crests of a wave is called this.
What is wavelength?
200
These waves have the lowest frequency and are used for communication.
What are radio waves?
200
These waves are used in cell phones and microwave ovens.
What are microwaves/radio waves?
200
AM and FM radio differ because this property changes in FM waves.
What is frequency?
300
This wave property is measured in hertz (Hz).
What is frequency?
300

When waves are closer together, the frequency is ___?
What is higher?
500
Arrange from lowest to highest energy: visible light, radio waves, gamma rays.
What are radio waves → visible light → gamma rays?
500
Radiation therapy uses these waves to treat cancer.
What are gamma rays?
500
