Pendulums and Springs
100
The distance between two consecutive crests or troughs in a wave.
What is Wavelength
100
This type of energy is at its maximum when a pendulum is at its highest point.
What is Potential Energy?
100
These waves require a medium to propagate.
What are mechanical waves?
100
If a wave's frequency is 5 Hz, its period is this many seconds.
What is 0.2 seconds?
100
The primary factor affecting a pendulum's period.
What is length?
200
This term describes how many wave cycles occur in one second.
What is frequency?
200
The wave property most closely associated with the loudness of sound.
What is amplitude?
200
In this type of wave, particles vibrate parallel to the direction of wave propagation.
What are longitudinal waves?
200
A wave with a frequency of 10 Hz and a wavelength of 2 m has this speed.
What is 20 m/s?
200
In a spring-mass system, this determines how quickly the system oscillates.
What is the spring constant and mass?
300
The time required for one complete wave cycle.
What is period?
300
When waves combine to increase their amplitude, this type of interference occurs.
What is constructive interference?
300
These waves can travel through a vacuum.
What are electromagnetic waves?
300
If a pendulum swings 30 times in 1 minute, its frequency in Hz is this.
What is 0.5 Hz?
300
For small angles, this type of motion describes a pendulum's swing.
What is simple harmonic motion?
400
This wave property is shown here.
What is Amplitude?
400
As amplitude increases, this property of a wave also increases.
What is energy?
400
A wave where particles vibrate perpendicular to the direction of wave propagation.
What are transverse waves?
400
A sound wave traveling at 340 m/s with a frequency of 440 Hz has this wavelength.
What is 0.773 m?
400
The presence of this bringing back something to equilibrium is the defining characteristic of Simple Harmonic Motion?
What is the restoring force?
500
This is how fast the motion of a particle travels through a given medium.
What is wave speed?
500
In simple harmonic motion, this energy remains constant (assuming no friction).
What is total energy (sum of kinetic and potential)?
500
A type of wave formed by the superposition of two waves traveling in opposite directions.
What are standing waves?
500
If a harmonic oscillator's mass is doubled, its period increases by this factor.
What is sqrt2
(or approximately 1.414)?
500
The formula for period of a pendulum.
What is T=2pisqrt(L/g) ?
