When two or more waves are at the same place at the same time, the resulting effect is called
an interference pattern on string
Where can you touch a standing wave on a rope without disturbing the wave?
at a node
a wave...
carries energy from one place to another has a period has a wavelength has a velocity
when a 100 Hz tuning fork is held above the opening of a tube, the only harmonics that are produced are 300 Hz and 500 Hz. the tube is...
closed at one end, open at the other
as the sound of a car's horn passes and moves away from you, the pitch of the horn seems to...
decrease
when the frequency of a wave is doubled, its wavelength
halves and the speed remains unchanged
Suppose a bug is jiggling up and down and swimming towards you at the same time. Compared to the frequency at which the bug is emitting waves, the frequency of the waves reaching you is
higher
When a pendulum clock is taken from sea level to the top of a high mountain, it will
increase
a wave created by shaking a top up and down is called a...
longitudinal wave
sound is an example of a...

standing waves can be set up
on the strings of musical instruments, by blowing across the top of a soda bottle, and in organ pipes.
the time needed for a wave to make one complete cycle is called its...
period
the Doppler effect is the change in observed frequency due to...
the motion of the source or observer
A Doppler effect occurs when a source of sound moves
toward you and away from you
the source of all wave motion is a...
