WAVE MATH
WAVE INTERACTION
WAVE INTERFERENCE
100
A periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium
What is a wave?
100
Individual particles travel perpendicular to the wave
What is Transverse wave?
100
Sound waves in air travel at approximately 330m/s. Calculate the frequency of a 2.5m-long sound wave.
What is 132Hz?
100
Bouncing back of a wave when it meets a surface or boundary
What is reflection?
100
The combination of two or more waves of the same frequency that result in a single wave.
What is interference?
200
Waves that require a medium
What are mechanical waves ?
200
Compressions and rarefactions

Type of a vibration that goes through a cycle usually up and down like a spring
What is simple harmonic motion?
400
This increases while wavelength decreases
What is frequency?
400
Water waves that are 10cm long pass a point in a tank at a rate of 3.75 waves/sec. What is their speed?
What is .375m/s?
400
Waves that pass from one medium to another bend like spoon in a glass of water.
What is refraction?
400
Two waves of slightly different frequencies interfere with each other produce this.
What are beats?
500
Waves are able to do work because they transmit _________
What is energy?
500
Change in frequency of a wave due to the motion of the source of the wave.
What is the Doppler Effect?
500
An air tube is 100 meters long. How long will it take for a pulse traveling at 331m/s to reach the other end?
What is .302s?
500
Waves that encounter a free end
What is simply reflect?
500
Wave reflected at the boundary of a medium
