Periodic Motion
This is the law that relates the force on a spring to the distance it is stretched.
Hooke's Law
This is the measurement of a wave from one point on the wave to another identical point on the wave. (E.g. from crest to crest or trough to trough.)
Wavelength
This is the quantity that denotes the intensity of sound as perceived by the ear. It is measured in decibels.
Loudness
What is the period of a 1.4m long pendulum?
2.375s

Piano
The period of a pendulum solely relies on these two quantities.
Length, Gravity
The energy of a wave is determined by the measurement of this wave property.
Amplitude
This is the physics phenomenon of something vibrating at its fundamental frequency. It is what creates standing waves of air in brass and woodwind instruments and standing waves along the strings of stringed instruments.
Resonance
When you add a 45-kg load to the trunk of your new car, you notice the back two shock springs compress 1.0cm. What is the spring constant of each of the springs?
22,000 N/m

Periodic or Simple Harmonic Motion is a byproduct of the physical law known as the Conservation of ______.
Mechanical Energy
Refraction
This type of instrument only allows multiples of standing waves in fourths. This causes odd numbers of frequencies/harmonics e.g. fundamental, third harmonic, fifth harmonic, etc.
If you drop a stone into a well that is 122.5m deep, how long after you drop the stone will it take for you to hear it hit the bottom of the well?
5.4s

A toy rocket with a mass of 150g is placed into a launcher that has a spring with a spring constant of 35 N/m. How far must the spring be compressed to launch this rocket 1m into the air?
30cm
When a wave hits a boundary and reflects, by how much does the phase shift from the incoming wave to the reflected wave. This is an angle either in degrees or radians.
180 degrees or pi radians
The sound emitted by bats has a wavelength of 3.5mm. What is the frequency of this wave? Remember, humans can detect frequencies through a range of 20Hz - 20,000Hz.
98,000Hz
63.7N

How must the length of a pendulum be changed to halve its period?
1/4th
The time needed for a water wave to change from the equilibrium level to the crest is 0.18s.
What fraction of a wavelength is this?
What is the period and frequency of the wave?
1/4th
0.72s and 1.4Hz
A vertical tube is filled with water and a tuning fork vibrates over the top of it. As the water level is lowered, resonance is heard at the 17cm and 49cm marks. What is the frequency of the tuning fork?
540Hz
A trumpet player sounds the note A (440Hz) while riding on a train. At the same time a trumpet plays the same note while standing next to you train station platform. You hear a beat frequency of 3.0Hz. How fast is the train moving toward you?
2.3 m/s
