Oscillations/Periodic Motion
A special unit used to measure frequency as it relates to oscillations per second.
What are Hertz?
A mass attached to a string.
What is a pendulum?
The highest point on a wave.
What is a crest?
A specific point along a standing wave where displacement is zero, appearing still on a vibrating medium.
What is a node?
The angle between maximum displacement and equilibrium.
What is amplitude?
The distance from one crest to the next.
What is wavelength?
Frequency and period share this kind of relationship.
What is an inverse relationship?
When velocity reaches a maximum.
What is maximum displacement?
V=f𝝺
What is the equation for the speed of a wave?
What restoring force must be proportional to in order for the vibration of an object about an equilibrium point to be simple harmonic motion.
What is displacement?
When acceleration reaches a maximum.
What is equilibrium?
When medium displacement is perpendiculal to the direction of energy transfer.
What are longitudinal waves?
Waves produced by the same frequency, amplitude, and wavelength traveling in opposite directions.
What are standing waves?
2π√(L/g)
What is the formula for the period of a pendulum?
The bending of waves around obstacles or through openings.
What is diffraction?
