Stadium Wave
A stadium wave is a transverse wave which is a wave that travels perpendicular to the direction of the particles within the wave. so when you see people do the wave at a basketball game, you can see the wave move across the entire stadium but the people alone stay in their seats.The greater the wave is, the more energy it has which means it has a bigger amplitude. The size of the amplitude can be measured from the baseline of the wave to the crest or to the trough. The number of waves in one second is the frequency and if you know the frequency and the wavelength, you can find the velocity of the wave by multiplying the two together. Not only are stadium waves found in a stadium but the noise from the screaming fans in the crowd create sound waves which are longitudinal waves where the particles move in the same direction as the wave!
