The Doppler Effect describes a frequency shift in reflected waves in proportion to the relative speed between the receiver and the reflected object.
For instance, in a radar speed trap, the frequency shift in reflected radio waves allows the unit to calculate the speed toward (higher frequency) or away from (lower frequency) the transmitter/receiver unit.
When you drive past a steady noise source, such a bell or a horn, the sound has a higher frequency as you approach and a lower frequency as you depart.

What affect if any does increasing the speed of the plunger have on the frequency of the waves?
Increasing the speed of the plunger will increase the frequency of the waves.
When working with waves frequency x equals speed?
When working with waves ... or even just talking about them ... (frequency) = (speed) divided by (wavelength) (wavelength) = (speed) divided by (frequency) (frequency) times (wavelength) = (speed)
How does a waves speed relate to its wavelength and frequency?
The product of (wavelength) times (frequency) is the speed.
How is the wavelength related to frequency for waves moving at a constant speed?
Whatever the wavelength and frequency happen to be, their product is always equal to the speed.
What is the speed of waves in water that are 2.5 meters apart and have a frequency of 4?
speed of a wave = wavelength x frequency = 2.5m x 4Hz = 10m/s
