A harmonic transverse wave function is given by y(x, t) = (0.850 m) sin (15.3x + 10.4t) where all values are in the appropriate SI units. a. What are the propagation speed and direction of the waves travel? b. What are the waves period and wavelength? c. What is the amplitude? d. If the amplitude is doubled, what happens to the speed of the wave?

Third harmonic frequency of a tube open both of its ends is 550 Hz. Determine the fourth harmonic frequency of this tube if one end is closed.

Third harmonic frequency of a tube open both of its ends is 640 Hz.  Determine the third harmonic frequency of this tube if one end is closed.

A rope has length L equals to 3.0 m and is fixed to both ends. What is the wave length pattern for the 5th harmonic?

Two strings, A and B, have respective mass densities A and py respectively. The linear mass density, Hp. of string-B is nine times that of string-A (H = 9). If both strings have the same fundamental frequency when kept at the same tension, then the ratio of their lengths L/LA is equal to: O 1/3 1/9 O 3 9.

a steel wire with a uniform tension T=600N, length L=2m and mass 8 kg. a) Find the elementary frequency of oscillation. b) if the maximum frequency that a person can hear is 10,000hz=f, what is the highest harmonic that this person can perceive?

You are exploring a newly discovered planet. The radiusof the planet is 7.20 * 107 m. You suspend a lead weight from thelower end of a light string that is 4.00 m long and has mass 0.0280 kg.You measure that it takes 0.0685 s for a transverse pulse to travel fromthe lower end to the upper end of the string. On the earth, for the samestring and lead weight, it takes 0.0390 s for a transverse pulse to travelthe length of the string. The weight of the string is small enough thatyou ignore its effect on the tension in the string. Assuming that the massof the planet is distributed with spherical symmetry, what is its mass?

Ex. How long must a closed end pipe be if it is to have a frequency of 600HZ in the 5th harmonic? O a) 71.5 cm

A violin string ? = 31.6 cm long and ? = 0.65 g⁄m linear mass density is tuned to play a La4 note at 440.0 Hz. This means that the string is at its fundamental oscillation mode, that is, you will be on that note without placing a finger on it. From this information: B. If the midpoint of the chord is displaced 1.80 mm transversely when found in the fundamental mode, what is the maximum speed ??á? of the midpoint of string?
