PLEASE HELP WILL MARK BRAINLIEST

Chemistry
1 answer:
Zielflug [23.3K]3 years ago
3 0

Answer:

1. There are 7 categories:

Radio waves, microwaves, infrared heat waves, visible light spectrum, ultraviolet waves, x-rays, gamma rays

2. They are all electromagnetic radiation.

3. The amount of energy the photons within them have.

4. The longer the wavelength, the less energy. The shorter the wavelength, the more energy. They are inversely proportional.

5. As the wavelength increases, the smaller the frequency. The shorter the wavelength, the larger the frequency. They are inversely proportional. Also, wavelength is measured in meters and frequency is measured in hertz (cycles per second). They are two of the 3 ways EM radiation is expressed.

6/7 Reds have the least. Violets have the most.

8. Violet has the shortest. Red has the longest.

9. Ultra Violet B-Rays (UV-B) are the harmful rays that cause sunburn.

10. Microwaves are generally used for radar technology.

11/12 You are exposed to all of the categories of the electromagnetic spectrum everyday of every year. You just can't see/feel them all.

hope this helps! stay happy and healthy, friend! :))
