Bill Nye: Waves Video & Notes
Hello! Today we watched a Bill Nye video about waves. We were given a sheet with questions on it. I'll post the questions up. I'll see you later. Peace!
1. What are three things that travel in waves?
> The three things that travel are light, sound and water.
2. What are three of the properties of waves?
> The three properties are wavelength, frequency and amplitude.
3. Do X-rays have higher or lower frequency than light waves?
> It has higher frequency than light waves.
4. Define wavelength.
> Wavelength is the distance between the two waves
5. What causes waves on the ocean?
> The wind causes the waves on the ocean.
6. What are the waves in the Earth called (Earthquake waves)?
> They are called seismic waves.
7. Define frequency.
> Frequency is how fast it's going and how often. Waves are close together and is shorter.
8. Define amplitude.
> Amplitude is the height of the waves.
9. What kind of wave travels by squeezing and spreading? (give an example)
>They are compression waves. An example is a spring.
10. What is it called when a wave bounces back and comes back to the source?
> It is called reflection.
11. What is Sonar?
> Sonar is a system that uses sound waves to find the distance of an object.
> The three things that travel are light, sound and water.

I see that you are done. I'll see you later. Peace!
