Node
Where can you touch a standing wave
All of the above
Standing waves can be set up
Higher

Motion of the source or observer
Doppler effect is the change in observed frequency due to
Stays the same
When a sound source moves towards you, what happens to the wave speed?
Amplitude
Some of a waves energy is always being dissipated as heat. This will reduce the waves
8 m
Amplitude of a particular wave is 4.0 m. Top to bottom disturbance is
Gain time

Halves
Double the frequency of a vibrating object it’s period
Shortens
Dip your finger more frequently the wavelength of waves
One wavelength
During a single period, the distance traveled by a wave is
Unchanged
