100
This value is zero when an oscillating particle on a spring passes through it's equilibrium position
What is either force, acceleration, elastic potential energy or position.
100
In terms of music, frequency is also known as this
What is pitch
100
The positive amplitude of a wave is also known as this.
What is a crest
100
A crest (pulse) is sent down a rope towards a fixed end. What happens to the pulse's amplitude and position?
What is return flipped over with the same amplitude
100
Two students are sitting on two different chairs that have rollers at the bottom. One student kicks the other student which causes them to both move backwards from their relative positions. Which of Newton's 3 laws explains this?
What is Newton's 3rd Law. If two objects touch, they will exert a force on each other that is equal in magnitude but opposite in direction
200
When an oscillating particle is oscillating back and forth, the maximum displacemnt from equilibrium is also known as this.
What is the amplitude
200
The interference between the sound frequency of two different sources will produce this
What is a beat
200
The superpositioning of waves is also known as this.
What is interference
200
A crest (pulse) is sent down a rope with a free end. What happens to the pulse's amplitude and position?
What is return on the same side with the same amplitude.
200
In an elastic collisiion, is momentum or kinetic energy conserved?
What is both. Momentum is ALWAYS conserved, but kinetic energy is not in an inelastic collision.
300
An oscillating particle oscillates back and forth 10 times in 5 seconds. The student would be able to measure this.
What is period or frequency
300
Another name for the 4th harmonic is this
What is the 3rd overtone
300
The distance from crest to crest or trough to trough is also known as this
What is a wavelength
300
A pulse is sent down a spring with a high spring constant and hits another spring attached with a lower spring constant. What happens to the pulse?
What is some of the pulse transfers to the second spring, now with a higher amplitude and the rest of the pulse returns back on the same side.
300
What type of wavelength would ultraviolet light produce (large or small)?
What is small. Since the Energy is high, and thus frequency is high, it will then produce a small wavelength
400
An oscillating particle oscillateds between positions A and C with position B the equilibrium position. What can you say about the particle's speed when it is at position A or C?
The object's speed is zero.
400
How many wavelengths will the 2nd harmonic produce in a tube that is open at both ends?
What is 1 wavelength
400
The interference of several crests with several troughs will produce this
What is a nodal line
400
A wave with a high frequency and small velocity is sent down a sring with a low spring constant. If same wave with the same frequency is sent down a different spring with a higher spring constant, what will happen to the velocity of the wave?
What is speed up or become higher.
400
The second harmonic is produced in a tube closed at both ends. If the length of the tube is 1.0 m and the speed of sound is 340 m/s, determine the fequency of the waves produced in the tube.
What is 340 Hz For the second harmonic, the wavelength is the length of the tube (1.0 m). If v= f * wavelength, then 340 m/s= 1.0 m (f) and f = 340 Hz

A 1.0 kg oscillating box attached to a 1.0 N/kg spring is forced to oscillate back and forth by displacing the box 5 cm from equilibrium. What is the box's velocity when it passes the equilibium position?
What is 0.05 m/s = 5 cm/s 1/2 k * x^2 = 1/2 m * v^ 2 k = 1, m = 1 x^2 = v^ 2 (.05 m)^2 = v^2
500
If the length of a tube is 1.0 m and the 2nd overtone is produced in the tube, determine the value of the wavelength.
What is 0.80 m 5/4 (wavelengh) = L 4/5 (L) = wavelength 4/5 (1.0 m) = wavelength = 0.80 m
500
The distance between two sources is 1.0 m and the interference point lies on the 2nd antinodal line. If the perpendicular distance from the source to the point is 2.0 m and the horizontal distance from the 0th antinodal line to the 2nd nodal line is 1.0 m, determine the wavelength
What is 0.5 m y * d/(m*L) = 1.0 m (1.0 m)/(2.0 m * 2.0 m) = 0.5 m
500
A pulse on a snakey is produced with a frequency of 5.0 m/s and a velocity of 1.0 m/s. If the frequency is doubled, determine the velcity of the new pulse
What is 1.0 m/s. The medium was not changed.
