Oscillations Flashcards
what measures frequency
hertz
What is the equation for period
1/f or time/cycles
What is the equation for frequency
1/t or cycles/time
What is the bottom of a wave called
the trough
What is the period
time to complete one cycle
what is the frequency
number of cyles per second
what is the top of the wave called
the crest
what is the highest/lowest point from the equilibrium distance called
the amplitude
waht is one wavelength
basically one cycle, before it repeats
what happens when the wavelength goes up
the frequency goes down
what happens when the wavelength goes down
the frequency goes up
what is harmonic motion
motion that repeats
what is an oscillator
an object or systems that moves with harmonic motion
what is a cycle
the unit of motion that repeats
what is an oscillation
a motion that repeats regularly, typically at a low speed
what is a vibration
a quick back and forth harmonic motion
what is the amplitude
a measurement of the size of a cycle
what is the equation for amplitude
a=1/2 times top-bottom
what is the crest
the top or highest point of the wave
what is a longitudinal wave
a wave whose oscillation are in the same direction as the wave travels
what is the trough
the bottom or lowest point on a wave
what is a transverse wave
a type of wave with oscillations that are perpendicular to the direction the wave travels
what is a standing wave
a resonance created by trapping a wave between boundaries that cause the wave to interfere with its own reflections
what is fundamental
the lowest natural frequency of a standing wave
