Electromagnetic Spectrum Review
The two diagrams below show the electromagnetic spectrum. Use the two diagrams to answer the
following questions.
Diagram 1:
Diagram 2:
Questions:
1) What is the electromagnetic spectrum?
2) How are the two diagrams different?
3) What parts of the electromagnetic spectrum can you see?
4) Which parts of the electromagnetic spectrum can you not see?
5) What makes red light different from blue light?
6) Which has a longer wavelength red or blue light?
7) Are X-rays longer or shorter than radio waves?
8) Are all gamma rays shorter than X-rays?
9) Which are longer AM radio waves or TV waves?
10) Can you see radio waves? How does its position on the electromagnetic spectrum demonstrate
this?
11) How does the wavelength of waves used for microwaves compare with the wavelength of waves
used for radar?
12) Which color of visible light has the longest wavelength?
13) Which color of visible light has the shortest wavelength?
14) Ultraviolet rays cause sunburn, X-rays penetrate deep inside our bodies, and gamma rays kill
cancer cells. What does this show you about how living things are affected by the shortest
wavelength in the electromagnetic spectrum?
