1. What does wavelength refer to? 2. What's the highest part of a wave called? Lowest part?
3. The longer the wavelength the the total energy of the wave.
4. The faster the frequency the the total energy of the wave.
5. Longer Wavelength + Lower Frequency =
6. The collection of all known frequencies and wavelengths of electromagnetic radiation is called what?
7. What waves are used for communication applications in television, radar, and mobile phones?
8. Which waves cause your skin to burn when you spend too much time in the sunlight?
9. What portion of the electromagnetic spectrum can be seen by humans?
10. Which color light has the shortest wavelength?

1. wavelength is the distance between two corresponding points on a wave

2. highest = crest, lowest = trough

3. lower

4. higher

5. this could tell you lots of things but given the context of the other questions I would say low energy or if it is asking what kind of wave, then probably radio waves.

6. Electromagnetic spectrum

7. radio waves

8. Ultraviolet

9. Visible light spectrum

10. violet

P.S. this is science (physics) not social studies

usually, however, secession was popular enough without the of community leaders. prominent unionists, on the other hand, were a major reason that texas did not secede before march 1861. the most important of these was sam houston, the governor of the state from 1859 to 1861.
