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...

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...

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...
