## Waves Lab

A pulse wave as shown in the first video. A pulse wave is just one wave that is emitted it is the shape of a half circle, or a wave.

Periodic wave is a wave that is constantly going, kind of like oscillating. It moves with a constant speed that does not change.

A transverse wave by definition is “a wave vibrating at right angles to the direction of its propagation”.

A longitudinal wave by definition is “a wave vibrating in the direction of propagation”, longitudinal waves include sound waves or vibrating waves.

This clip is demonstrating destructive interference, one person flung the slinky down and the other flung the slinky upward, when the waves meet in the middle they cancel eachother out making the slinky take the form of a flat line once again.

This clip demonstrated constructive interference. Both group members flung the slinky in the same direction (up or down) at the same time so that the waves would collide, when the waves collides they constructed a bigger wave, like they combine forces.

In our third trial we rapidly slinged the slinky back and forth, our goal was to find how many node points we would make with our slinky, a node point is basically one wave, if it takes 3 waves to reach the other end the slinky has 3 node points. It is a lot easier to see if the slinky is going at super rapid speeds but we counted 3 node points on our slinky.
