Periodic Motion
The number of cycles per second, measured in Hertz.
What is frequency?
The wave equation that relates velocity, frequency and wavelength to each other.
What is v=f (lambda)?
What is 331 m/s?
True or False: Frequency changes when sound enters a new medium.
False.
This is when waves overlap and amplitudes add.
What is constructive interference?
The frequency with a system completes 24 cycles in 8 seconds.
What is 3 Hz?
The speed of a wave that has a wavelength of 2 m and a frequency of 10 Hz.
What is 20 m/s?
The wavelength of a 331 Hz sound wave in air at STP.
What is 1.0 m?
This happens to the wavelength of a sound wave when it enters a faster (denser) medium.
The wavelength increases.
When waves overlap and amplitudes subtract.
What is destructive interference?
The period of a wave that has a frequency of 5 Hz.
What is 0.20s?
The wavelength of a wave that travels at 30 m/s and has a frequency of 6 Hz.
What is 5 m?
The frequency of a sound wave in air at STP with a wavelength of 0.75 m.
What is 441 Hz?
The wavelength of a sound wave that is traveling at 1481 m/s at 500 Hz.
What is 2.96 m?
This is the maximum possible amplitude when a +3 cm and a +4 cm wave overlap.
What is 7 cm.
The amount of oscillations that occur in 10 seconds for a mass oscillating with a period of 0.20s.
What is 50 oscillations?
The wavelength of a wave that travels 120 m in 8 s and has a frequency of 5 Hz.
What is 3 m?
The wavelength of a 516 Hz sound wave traveling in air at STP.
The amplitude of a sound wave as it travels from a medium of steel to water. (increase, decrease, stays the same, unknowable)
What stays the same?
How two waves line up if each have an amplitude of 5 cm, but when they interfere, they completely cancel.
Crest to Trough/Peak to Vally/180o out of phase.
The amount of oscillations completed in 2 minutes if a spring completes 150 oscillations in 30 s.
What is 600 oscillations?
What is 120 m?
The wavelength of a sound wave that travels 662 m in 2 s and has a frequency of 5 Hz.
What is 66.2 m?
This is the wavelength difference between a 400Hz sound wave in air (speed is 331 m/s) and a 400Hz sound wave in water (speed is 1481 m/s).
What is 2.88 m?
This is the combined amplitude of two sound waves with 6 cm amplitudes that overlap constructively.
What is 12 cm?
