Transverse waves are created by a vibration or a disturbance.
These waves are important because without them, light wouldn't travel to our eyes or we wouldn't know what seismic S-waves are.
Longitudinal waves are created by a vibration or a disturbance.
These waves are important because they make up sound waves, pressure waves and seismic P-waves (earthquakes). We wouldn't hear anymore, talking, sounds to warn us and measuring earthquakes wouldn't exist.
The angle of the second incidence was 165 degrees. The angle of reflection is also 165 degrees.
The angle of the third incidence was 100 degrees. The angle of reflection is 100 degrees.
The Law of Reflection
The initial gap in the first video was a narrow opening so that flow of the wave looked much skinnier. In the second video, the gap had increased and the wave became wider.
