1. The following figure is a snapshot graph at t=0 s of
two waves approaching each other at
1.0 m/s. Draw 2 snapshot graphs showing the string at t=3 s and
t=4 s.
2. The following figure is a snapshot graph at t=0 s of
two waves approaching each other at
1.0 m/s. Draw the snapshot graph showing the string at t=6 s and
t=8 s.

3. The following figure shows a standing wave oscillating
at 100 Hz on a string. What is thewave speed?
4. Standing waves on a 1.0 m long string that is fixed at
both ends are seen at successive
frequencies of 36 Hz and 48 Hz.
a.
What are the fundamental frequency and the wave
speed? b. Draw the standing-wave pattern when the string
oscillates at 48 Hz.
5.
A clarinet is 66.0 cm long. A flute is nearly the same length,
with 63.5 cm between thehold the player blows across and the end of
the flute. What are the frequencies of the
lowest note and the next higher harmonic on a flute and on a
clarinet? The speed of soundin warm air is 350 m/s.
