question
When is the kinetic energy of the mass a maximum?
answer
When the spring is at its unweighted length (not stretched or compressed)
question
How does the frequency of oscillation depend on the mass of the weight?
answer
The frequency decreases as the mass increases
question
How does the frequency depend on the amplitude of oscillation?
answer
The frequency is independent of the amplitude.
question
How does the frequency of oscillation depend on the spring constant?
answer
The frequency increases as the spring constant increases.
question
If you decrease the distance between successive crests of a wave, this changes..?
answer
Both the wavelength and the frequency.
question
Example of a longitudinal wave?
answer
Sound wave
question
If the period of the oscillator doubles, what happens to the wavelength and wave speed?
answer
The wavelength doubled but the wave speed is unchanged.
question
If the amplitude of the oscillator doubles, what happens to the wavelength and wave speed?
answer
They are both unchanged.
question
A 100Hz sound wave is traveling through the air, if the frequency is increased to 200Hz, this will ______ the wavelength.
answer
Decrease
