Question

Consider the phase speed of transverse waves on a wire, with the
changes listed below. Answer `true' (T), `false' (F), or `cannot
tell' (C) to each of the five statements.

E.g., if the answer to the first statement is T and to the rest, F,
enter TFFFF.

- If the mass of the wire is doubled and the tension and length remain the same, the phase speed of the transverse wave decreases by a factor of 2.
- If the tension in the wire is doubled, the phase speed of the transverse wave doubles.
- If the tension is doubled and the mass of the wire is doubled (assuming the length remains the same), then the phase speed remains the same.
- If the tension is increased and the length of the wire is increased (assuming the mass remains the same), then the phase speed increases.
- If the length of the wire increases by a factor of 2 and the tension and mass remain the same, the phase speed of the transverse wave increases by a factor of square root of 2.

A transverse wave propagates in a very long wire of mass per
unit length 4*10^-3 kg/m and under tension of 360 N. An observer
next to the wire notices 10 wave peaks (or crests) passing her in a
time of 2 seconds moving to the left.
a) If at t=0 and x=0 the displacement assumes its maximum value
of 1mm, what is the explicit equation for the wave?
b) Calculate the maximum longitudinal velocity for an
infinitesimal segment of the...

The waves that stay in the middle by reflecting and changing
phase, without canceling out, are called standing waves because
they take shape that does not vary with time.
6- The set of free frequencies in which a system can vibrate is
known as natural frequencies.
7- Transverse waves in the string vibrate to the medium in the
direction of wave propagation.
The wavelength vs frequency graph has the form of? A- straight
line B- circle C- Parable D- Square...

1.). Two sinusoidal waves are moving through a medium in the
same direction, both having amplitudes of 4.00 cm, a wavelength of
3.50 m, and a period of 6.25 s, but one has a phase shift of an
angle φ. What is the phase shift (in rad) if the resultant
wave has an amplitude of 4.00 cm? Hint: Use the trig identity
2.). Consider two sinusoidal sine waves traveling along a
string, modeled as
y1(x, t) = (0.2 m)sin[(6 m−1)x...

Consider a transverse harmonic wave travelling along a string.
Enter true (T) or false (F) for the following statements. For
example, if the first statement is true and the rest false, enter
TFF. You have 4 tries.
Increasing the amplitude of the wave increases its
frequency.
If a wave with a frequency of 10 Hz travels along a string with
a mass per unit length of 40 g/m stretched to a tension of 100 N,
its wavelength is...

Consider a shallow-water wave of length 1.5km propagating in an
ocean that is 62.5m deep . The speed of the wave is 25m/s and the
period T= 60 sec .
a) Now suppose that this wave propagates into a region in which
there is a current of strength U that opposes the wave propagation.
Explain how this modifies the dispersion relation and the wave
speed.
b) Assuming that the wave’s frequency ω remains constant, create
a plot of the wavelength...

A simple pendulum suspended in a rocket ship has a period T0.
Assume that the rocket ship is near the earth in a uniform
gravitational field. T/F 1.If the ship accelerates upward, the
period increases. 2.If the ship accelerates downward at 9.81 m/s2,
the pendulum will no longer oscillate. 3.If the length of the
pendulum is doubled, the new period will be: square root of 2 times
T0. 4.If the mass of the pendulum doubles, the period increases.
5..If the...
