Electromagnetic waves are all around us T or F
2. Radio waves can be as long as a mountain base T or F
3. Electromagnetic waves and ocean wave both have energy T or F
4. All wavelengths are the same distance T or F
5. Frequency is how fast waves travel per second. T or F
6. Adding more or faster frequency gives more energy T or F
7. Gamma waves has the highest “most” frequency T or F
8. Our eyes only see radio waves T or F
9. In the visible spectrum some wavelengths are reflected, and some are absorbed from an object T or F
10. We use the EM spectrum to learn more about the Earth, Sun and universe T or F

2. True, 3 True, 4 Trues, 5 False, 6 True, 7 True, 8 False, 9 True, 10 True

Explanation:

3. True , Electromagnetic waves have electric and magnetic energy while ocean wave have kinetic energy which is then converted into electrical energy.  

4. True, the distance between all the wavelength is same until and unless it not dampened or attenuated or amplified.  

5. False, Frequency measures the number of times an event takes place in a given time period.  

6.   True, the higher is the frequency , the more will be the energy

7. True, Gamma waves have highest frequency

8. False, our eyes could see only visible spectrum wavelengths

9. True, some object or surfaces reflect the wavelength while some absorb it.  

10.  True, all cosmic researches are driven by EM waves theory and related logic.

really dont know just need some points
