Unit 9: Waves

Today !
we learned about waves~~~~~~
So what exactly is a wave?
Well a vibration, is more of a "wiggle in time", while a wave is a "wiggle in time" and in space! It is basically this energy that moves through space and time in an undulating motion.
So how long is one wave length?

ta da! So from the first point to the second point is one wavelength. The wave started at point A and ended up in the same spot at point B (on the horizon line). 

So lets look at a certain situation to explain constructive interference (one of the interferences I can actually demonstrate with this wave and penguin example). So penguin guy is surfin and he notices a wave of the exact same size is coming towards him in the opposite direction. What will happen when the two waves collide?

The two waves collide and make a super massive one! But it doesnt last for long.. The two individual waves will then continue to go their separate ways, never meeting again. : ' (
