(red) visible light is a tiny part of the electromagnetic spectrum. (indigo) ultraviolet has less energy than visible light. (green) which of the following statements is false? electromagnetic waves are the only type of wave that can travel through space. (yellow) humans can only see.0035% of the electromagnetic spectrum. (red) gamma waves are the least dangerous type of electromagnetic wave. (sky blue)

Explanation:

1. The entire range of electromagnetic waves is called the electromagnetic spectrum.
2. Electromagnetic waves are placed from highest to lowest energy.
3. The human eye can see waves in the visible part of the electromagnetic spectrum.
4. Radio waves have the longest wavelength and lowest energy.
5. Gamma rays have the shortest wavelength and highest energy.
6. Gamma rays are used to treat cancer.
7. A cell - phone emits microwaves.
8. Snakes use infrared waves to find food.
9. Sunburns are caused by ultraviolet waves.
10. The acronym for the visible spectrum colors is ROY G. BIV.
11. Visible light is a tiny part of the electromagnetic spectrum is true.
12. Electromagnetic waves are not the only type of wave that can travel through space, so this statement is false. Gamma waves are highly dangerous. Humans can only see a very small portion of the electromagnetic spectrum.
