If the period of the oscillator doubles, what happens to the wavelength and wave speed?
answer
The wavelength doubles but the wave speed is unchanged.
question
If the amplitude of the oscillator doubles, what happens to the wavelength and wave speed?
answer
Both wavelength and wave speed are unchanged.
-When waves travel along a string, the wave speed remains unchanged, unless the properties of the string are changed. The wavelength can be varied only by changing the frequency, or alternatively the period, of the oscillator that creates the waves.
question
If the strings have different thicknesses, which of the following parameters, if any, will be different in the two strings?
answer
wave speed and wavelength
question
amplitude
answer
length of the peak
question
frequency
answer
number of waves per second
