What are waves?
Rhythmic disturbances that carry energy without carrying matter.

What is a crest?
the highest part of a transverse wave
100
What is a reflection?
The bouncing back of an object or a wave when it hits a surface through which it cannot pass

What is the equation for wave speed?

wave speed = wavelength x frequency

200
What are mechanical waves?
The type of waves that use matter to transfer energy.
200
What is a wavelength?
the distance between crest to crest or trough to trough in a transverse wave or from compression to compression or rarefaction to rarefaction in a compressional wave.
200
What is refraction?
the bending of waves due to a change in speed

A sound wave has a wavelength of 2 m and a frequency of 20 Hz. What is the speed of the wave?

40 m/s

300
What is a rarefaction?
The parts where the coils or particles are spread out in a longitudinal or compressional wave
300
What is frequency?
the number of complete waves that pass a given point in a certain amount of time
300
What is diffraction.
The bending of waves as they move around a barrier or pass through an opening

What is a medium?
The material through which a wave travels
400

What is a trough?

the lowest point on a wave

What is constructive interference?
The interference that occurs when waves combine to make a wave with a larger amplitude

What is Amplitude?

a word used to describe that amount of energy a wave carries or the height of a wave
