Question

Tell me what most important to write down
"Imagine placing this jump rope flat on the ground. Then pick the rope up on one end and move it up and down. When you do this, you would observe a pattern that modeled the movement of a wave. Another great example of something that produces wavelike patterns is a coiled spring toy. Examine the picture here and notice the wavelike pattern that the toy is producing."

Answer 1

Tell me what most important to write down
A wave is a repeating pattern. Waves have a repeating pattern with several key properties. One of those key properties is wavelength. The wavelength is the distance between one crest of a wave to the next crest of a wave.

Answer 2

Tell me what most important to write down
Frequency is another key property of waves. When you look at the frequency of a wave, you can examine the number of times the pattern in the wave repeats itself over a given amount of time. The more the pattern repeats itself in a given amount of time, the higher the frequency. Which wave in this picture has a greater frequency? The bottom picture repeats itself more often than the top wave. Therefore, the wave in the bottom picture has a higher frequency.
