high point of a wave

What is the crest?
the bouncing back of a wave off a surface

What is reflection?
When two waves meet at the crest, it creates this kind of interference:

What is Constructive Interference?
low point of a wave

What is trough?
disturbance that transfers energy from one place to another without transferring matter
what are waves?
change in direction of a wave that occurs when a wave changes speed moving from one medium to another
What is refraction?
occurs when the crest of one wave interferes with the trough of another wave

What is destructive interference?
distance between two neighboring crests or troughs

What is wavelength?
In this kind of wave, the particles of the medium move up and down at right angles to the direction of motion of the wave

What is transverse?
sound waves are this type of wave (transverse or longitudinal)
What is longitudinal wave?
radio waves, light waves, microwaves, ultraviolet waves, and gamma waves are all this type of wave
what are electromagnetic waves
the height of a wave

What is amplitude?
In this kind of wave, the particles of the medium move back and forth in the direction of the wave.

What is longitudinal or compressional?
This is the formula for wave speed
wave speed = wavelength x frequency
two parts of a longitudinal (comprassional) wave

What is compression and rarefaction?
This forms when a wave continues to resonate:
What is a Standing Wave
