Question

A taut 0.750 m string is plucked at one end, and the pulse takes 0.150 s to travel to the

- pposite end and back again.
- What is the wave speed on the string? (2)
- What are the three lowest frequencies for standing waves on the string? (4)
- If a string four times the mass density is used instead, what is the new lowest frequency? (3)
- Bonus: When the pulse in the description reaches the opposite end, is it inverted or upright when it reflects? (1)

A composite string is made up of a short length of heavy string
(µ1) and a very very long length of much lighter string (µ2 µ1).
The light end of the string is attached to a pole very far away.
The string is held under tension by passing the heavy end over a
pulley and attaching it to a bag full of sand. The heavy segment of
the string has length L (between the pulley and the knot between
the...

A guitar string of length 72.8 cm (which might be out of tune)
has been plucked and is producing a note of frequency 334 Hz. (a)
What is the speed of transverse traveling waves on this guitar
string? Give your answer in m/s. HINT: The note you hear is
produced by the vibrational mode of the string which has the
fundamental (lowest possible) frequency. Draw a picture of the
string vibrating in that mode and determine the wavelength of the...

A tall, thin, slightly flexible steel post of length 5.83 m is
fixed upright with one end in the ground. The top end of the post
is free to move. What is the lowest frequency standing wave that
can be formed on the post, if the wave propagation speed in the
steel is 2730 m/s?
Suppose that a standing wave on the post gives rise to a sound
wave of the same frequency. A person would be able to hear...

A 4.70-m-long string that is fixed at one end and attached to a
long string of negligible mass at the other end is vibrating in its
fifth harmonic, which has a frequency of 428 Hz. The amplitude of
the motion at each antinode is 2.82 cm.
(a) What is the wavelength of this wave?
?5 = m
(b) What is the wave number?
k5 = m?1
(c) What is the angular frequency?
?5 = s?1
(d) Write the wave function for this standing...

A 1.40-m string of weight 0.0124 N is tied to the ceiling at its
upper end, and the lower end supports a weight W. Neglect the very
small variation in tension along the length of the string that is
produced by the weight of the string. When you pluck the string
slightly, the waves traveling up the string obey the equation
y(x,t)=(8.50mm)cos(172rad⋅m−1x−2730rad⋅s−1t)
Assume that the tension of the string is constant and equal to
W.
a) How much time does...

1) Selena measures the total distance between the nodes on
either end of a standing wave pattern to be 0.75 m, and she records
that there were three antinodes between the endpoints. When she
calculates half of the wavelength of the pattern, using these
measurements, what is the result? Express your answer in
meters.
4) Jerome has added mass to the holder and created the standing
wave pattern. He observes that the string appears to have nodes
where it meets...

1. A cord of mass 0.65 kg is stretched between two supports 8.0
m apart. If the tension in the cord is 140 N, how long will it take
a pulse to travel from one support to the other?
2. A 50.0 Kg ball hangs from a steel wire 1.00 mm in diameter
and 6.00 m long. What would be the speed of a wave in the steel
wire?
3. The intensity of an earthquake wave passing through the earth...
