It is the material that a wave travels through?
What is a medium?
100
The displacement of a wave
What is the amplitude?
100

When two waves interfere, the resulting displacement (amplitude) of the medium at any location is the sum of the displacements of the individual waves at that same location.

What is superposition?

100

Produced by the vibration of material objects.

What is sound?

100

All angles in reflection and refraction problems are measured from this line.

What is the normal line?

200

Waves is the transfer of _________.

What is energy?

200
The distance in meters from the crest of one wave to the crest of another.
What is a wavelength?
200

Interference when a crest overlaps a crest.

What is constructive interference?

200

Sound travels faster in most solids than in air due to the ___________________

What is elasticity?

200

This is the angle created by the initial wave when compared to the normal.

What is the angle of incidence?

300
Type of wave that requires a medium
What is a mechanical wave?
300
The number of waves that pass in second.
What is frequency?
300
Interference when a crest overlaps a trough
What is destructive interference?
300

Characteristic that influences the volume of a sound

What is the amplitude?

300

This variable determines how much a wave will bend when entering a new medium

What is the index of refraction?

400

Type of wave that does not use a medium.

What is a electromagnetic wave?

400
The equation for wave speed?
What is v=fλ?
400

Location of a standing wave where there is no displacement.

What is a node?

400

Characteristic that dictates the pitch (note) of a sound

What is frequency?

400

If n of a new medium is smaller than n for the original medium, a wave will bend_____________ from the normal line.

What is away?

500
A wave where the direction of motion is the same as the direction of particle motion
What is a longitudinal wave?
500
Waves travel at a speed of 4 m/s at a frequency of 2 Hz. Therefore the wavelength must be_________.
What is 2m?
500
Occurs when a wave reflects upon itself and interference causes the pattern
What is a standing wave?
500

In space, sound (can/cannot) be heard because ________________________.

What is cannot be heard because there is no medium?

500

If a light ray is traveling from air into water at an angle of incidence of 20 degrees, what will be the angle of refraction?

What is 15 degrees?
