The first type of wave we demonstrated was the pulse wave. A pulse wave is a wave that does not repeat.

The next wave we demonstrated was a periodic wave. A periodic wave repeats at regular intervals.

The next wave we demonstrated was a transverse wave. Transverse waves are waves that are moving side to side after being pulled one direction.

The next wave we demonstrated was the longitudinal wave. Longitudinal waves occur when the spring is compressed and then let go.

Next we demonstrated a destructive interference between waves. This happens when the crest of a wave meets the trough of another wave causing the waves to cancel out.

Then we demonstrated constructive interference between waves. Constructive interference is when the crests of multiple waves meet or the troughs of multiple waves meet causing the waves to combine their energies.

Next we showed standing waves. Standing waves have certain points in the wave that remain at rest throughout the interference. These points are called nodes. Some waves have only 2 nodes and others have a lot more.

1. Increasing the tension of the slinky/string will increase the speed of the wave.
2. When a crest hits a boundary, it reflects as a trough.
3. By increasing the frequency, you will decrease the wavelength. This means that when you decrease the frequency, the wavelength increases.
