Air Temperature Affects 512HZ Tuning Fork Resonance

Click For Summary

Homework Help Overview

The discussion revolves around the relationship between air temperature and the resonance of a 512Hz tuning fork when placed over a bottle with water. The original poster is trying to determine the temperature of the air based on the water level corresponding to the first harmonic.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the relationship between wave speed, wavelength, and frequency. Questions arise regarding the wavelength in relation to the water level and the characteristics of a closed pipe's fundamental frequency.

Discussion Status

The discussion is ongoing, with participants exploring relevant equations and concepts related to wave behavior in closed pipes. Some guidance has been offered regarding the relationship between pipe length and wavelength, but no consensus or resolution has been reached.

Contextual Notes

Participants are working with limited information and are questioning the assumptions related to the wavelength and the properties of sound in a closed system.

Homework Statement


a 512HZ tuning fork held over a bottle receives its 1st harmonic when the level of water is 17cm from the bottle opening. what is the temp of the air


Homework Equations


sound equation


The Attempt at a Solution


I have no idea where to start.
 
Physics news on Phys.org
Do you know an equation that relates the speed of a wave to the wavelength and frequency?
 
wavelength

is 17cm the wave length
 
What do you know about thewavelength of the fundamental frequency of a closed pipe?
 
not much all i know is that there's some kind of pattern
 
for a pipe closed at one end the fundamental frequency has a wavelength 4 times the pipe length.
