The Three Types of Waves
Waves transfer or transmit energy from one place to another.
3 Types of Mechanical Waves include Transverse, Longitudinal, and Surface Waves. All of which need a medium in order to travel, opposed to light waves which do not need a medium to travel.
Medium: A substance which a wave can use to travel such as particles.
Crest: The top point on a wave , like the crest of a hill.
Trough: The bottom point between the two crests of a wave.
Wavelength: Best known as the distance between two crests of a wave.
Amplitude: The magnitude of the wave, from the crest to the equilibrium or also known as the time per cycle.
Examples of Transverse Waves Include Sound Waves
Longitudinal Wave: A wave that vibrates in the direction of propagation
Rarefaction: The lessening of density in a substance (where the wavelength is spread further apart).
Compression: The increase in density in a certain area (wavelengths are closer together).
Surface Wave: Where two media are in contact (ex: air & water)
Energy: the ability to perform a designated task
