A length of organ pipe is closed at one end. If the speed of sound is 344 m/s, what length of pipe is needed to obtain a funda- mental frequency of 70 Hz? Answer in units of m.
Physics
A pipe that is open at both ends has a fundamental frequency of 330 Hz when the speed of sound in air is 333 m/s. What is the length of this pipe? Answer in units of cm. What is the second harmonic? What is the third harmonic? Answer in units of Hz. What is the fundamental fre...

The length of a string is 344 cm. The string is held fixed at each end. The string vibrates in two sections; i.e., the string has two antin- odes, and the string vibrates at 130 Hz. Find the wavelength answer in m What is the fundamental frequency? Answer in units of Hz.
Physics
To demonstrate standing waves, one end of a string is attached to a tuning fork with frequency 120 Hz. The other end of the string passes over a pulley and is connected to a suspended mass M, as shown. The value of M is such that the standing wave pattern has eight loops “...
