1) John is holding a tuning fork that is creating a 663-Hz sound. Jack holds an identical tuning fork that is creating the same frequency sound. If John starts walking toward Jack at a speed of 3.81 m/s, what is the beat frequency detected by Jack? Answer in Hz
2)An organ player in a cathedral plays pipes X and Y, which are both open at both ends. Pipe X has a length of 0.823 m. They both vibrate at their fundamental frequencies, and a beat frequency of 5.07 Hz is detected. What are the two possible lengths of pipe Y? Longer and shorter lengths in m.

Tuning fork 1 Tuning fork 2 Bob 9.0 m - 3.0m - Two identical tuning forks are positioned 9.0 m apart, and emit sound equally in all directions. Alex is standing exactly halfway between the tuning forks, and Bob is standing 3.0 m to the right of the rightmost tuning fork. Alex hears an intensity of one tuning fork of 55 dB playing at 300 Hz. 1. How much power is emitted as sound by one tuning fork? 2. When...

6.) A person holding a 325 Hz tuning fork walks towards a wall at 1.33 m/s. What beat frequency is heard by the person due to the difference in frequency of the tuning fork and its echo off the wall? (Hint: The person is a moving source, but they still hear the tuning fork at the original frequency). (2.5 Hz)

A tuning fork generates sound waves with a frequency of 232 Hz. The waves travel in opposite directions along a hallway, are reflected by walls, and return. The hallway is 42.0 m long and the tuning fork is located 14.0 m from one end. What is the phase difference between the reflected waves when they meet at the tuning fork? The speed of sound in air is 343 m/s.

A bicyclist is moving toward a sheer wall while holding a tuning fork rated at 464 Hz. If the bicyclist detects a beat frequency of 6 Hz (between the waves coming directly from the tuning fork and the echo waves coming from the sheer wall), calculate the speed of the bicycle. Assume the speed of sound is 343 m/s.

A tuning fork generates sound waves with a frequency of 252 Hz. The waves travel in opposite directions along a hallway, are reflected by walls, and return. The hallway is 47.0 m long and the tuning fork is located 14.0 m from one end. What is the phase difference between the reflected waves when they meet at the tuning fork? The speed of sound in air is 343 m/s. (I got 304.9 and it says "Your response is within 10%...

You have pipes of various lengths and openings and want to select 2 pipes (1 open-open and 1 open-closed) so your 440 Hz tuning fork will vibrate both perfectly at their first resonant points. The speed of sound in air is 343 m/s. a) What are the lengths of each of these two pipes? b) Draw a picture of the wave in both pipes and clearly indicate the nodes and antinodes of the wave inside both pipes. c) How much...

A pipe open only at one end has a fundamental frequency of 254 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Now when both pipes vibrate at their fundamental frequencies, a beat frequency of 20 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 345 m/s.

A pipe open only at one end has a fundamental frequency of 240 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Now when both pipes vibrate at their fundamental frequencies, a beat frequency of 16 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 345 m/s.
