Waves
By Brandon, Ervin & Sydney
Transverse Waves
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
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.
Spherical Wave Calulation
A spherical wave is a vibration that creates a circular formation of waves, for example like you see when a water drop hits the surface of water, it creates a wave in the form of a circle.
Wavelength= .9cm
Frequency= 21H
Wave Speed= 18.9cm/s
Plane Wave Calulation
A plane wave is your average flowing wave, for example like you see in the ocean.
Frequency= 25H
Wave Speed= 22.5cm/s
Reflection Waves
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
Double Slit Interference
Dual Pin Interference
Wave Diffraction
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.
