If the frequency of a wave is increased, what happens
to its wavelength?
If the frequency of a wave is doubled, what happens
to its wavelength?
If you put your fingertip in a pool of water and repeatedly
move it up and down, you will create circular water waves that
move out from that point. What will happen to the wavelength
of these waves if you move your finger up and down more slowly
(or less frequently)?
As a wave goes by, how far does it move during one
period?
If the amplitude of a wave is increased 10%, what happens
to the wavespeed?
Can a transverse wave travel along a Slinky toy?
Can a sound wave be polarized?
Can a light wave be polarized?
If exactly the same signal is sent to two speakers,
what will a listener hear as she walks along a line parallel to
the speakers (as illustrated in the nearby sketch)?
When standing waves are present on a string, are all
the loops the same length?
How should you wiggle the nozzle of a water hose so
the stream of water is approximately a sinusodial wave?
Why does the amplitude of a water wave decrease as
the wave spreads out from its source?
How does the frequency of a wave compare to the frequency
of the source that created it?
Carefully hold a metal rod horizontally at its mid-point.
If you then strike it horizontally on its end, what kind of wave
will be created in the rod? If you then strike it vertically
on its end, what kind of wave will be created in the rod? Will
the sound you hear be the same or different for these two cases?
Why?
