A student holds a tuning fork oscillating at 256 Hz. He walks toward a wall at a constant speed of 1.09 m/s. (a) What beat frequency does he observe between the tuning fork and its echo? ?Hz (b) How fast must he walk away from the wall to observe a beat frequency of 6.00 Hz? ?m/s

A sinusoidal wave is traveling along a rope. The oscillator that generates the wave completes 45.0 vibrations in 35.0 s. A given crest of the wave travels 410 cm along the rope in 12.0 s. What is the wavelength of the wave?

A fisherman notices that his boat is moving up and down in a periodic way because of waves on thesurface of the water. It takes 4.0 s for the boat to travelfrom its highest point to its lowest, a total distanceof 3.0 m. The fisherman sees that the wave crests are spaced 8.0 m apart. The frequency is______ Hz

When a string that is 2m long is connected between two supports and vibrated at 176 Hz it is observed to produce 8 antinodes. If the tension on the string is 77.5 N what would the total mass of the string be?

A string with a length of 1.65 m is fixed at both ends. It is then allowed to oscillate transversely such that there are 1 nodes between the ends, with an amplitude of 16.6 cm. What is the maximum transverse displacement of the string 0.967 m from one end? Please give answer in units of cm.

A student holds a tuning fork oscillating at 256 Hz. He walks toward a wall at a constant speed of 1.45 m/s. (a) What beat frequency does he observe between the tuning fork and its echo? 0.08 x Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. Hz (b) How fast must he walk away from the wall to observe a beat frequency of 5.60 Hz? 5.60 X Your response differs from the correct answer by more than 10%. Double check your calculations. m/s

A harmonic wave is traveling along a rope. It is observed that the oscillator that generates the wave completes 43.0 vibrations in 34.0 s. Also, a given maximum travels 430 cm along the rope in 9.0 s. What is the wavelength?

A Slinky stretched to 4.00 m carries a wave along its length. (a) How fast does the wave propagate if it takes 2.4 s to travel down the Slinky and back again? (b) In the same Slinky, a standing wave with four nodes and three antinodes is set vibrating. What is the frequency of vibrations?

Two timpani (tunable drums) are played at the same time. One is correctly turned so that when it is struck, sound is produced that has a wavelength of 2.20m. If the speed of sound is 343m/s, what beat frequency is heard?

Two identical piano wires have a fundamental frequency of 555 Hz when kept under the same tension. What fractional increase in the tension of one wire will lead to the occurrence of 7 beats/s when both wires oscillate simultaneously?
