It can't fix a car, but this does requires a medium through which to travel.
What is a mechanical wave?
100
This is the highest part of a transverse wave, not toothpaste.
What is a crest?
100
The maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium.
What is amplitude?
100
The bouncing back of an object or a wave when it hits a surface through which it cannot pass.
What is reflection?
100
The material (not too big, and not too small) through which a wave travels.
What is a medium?
200
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels.
What is a transverse wave?
200
The lowest part of a transverse wave.
What is a trough?
200
The distance between two corresponding parts of a wave.
What is wavelength?
200
The bending of waves as they enter a new medium at an angle.
What is refraction?
200
A disturbance that transfers energy from place to place.
What is a wave?
300
A wave that moves the medium in a direction parallel to the direction in which the wave travels.
What is a longitudinal wave?
300
The part of a longitudinal wave where the particles of the medium are close together.
What is a compression?
300
The number of complete waves that pass a given point in a certain amount of time.
What is frequency?
300
What happens to an image when light is reflected off of the hollow part of a spoon?
it gets inverted (upside down)
300
Besides transferring energy, why are waves useful to people.
transfer information

400
Unit of measurement for frequency.
What is a hertz (Hz)?
400
a microscope refracts (bends) light waves in order to do what?
magnify it.
400
A huge surface wave on the ocean caused by an underwater earthquake.
What is a tsunami?
500
A longitudinal seismic wave.
What is a P wave?
500
Auto-tune which is a digital sound editing tool. Can make bad singers sound good.
What in terms of a sound wave's characteristics does this software change?
change frequency or pitch from being off to on key.
