Frequency of a pressure vs time chart

Click For Summary
SUMMARY

The discussion focuses on determining the frequency and wavelength of a sound wave represented in a pressure vs. time chart. The user applied the formula frequency = speed / wavelength, using a speed of 343 m/s, but encountered difficulties in calculating the wavelength. Participants clarified that the graph does not resemble sine or cosine functions and suggested finding the period to calculate the frequency accurately.

PREREQUISITES
  • Understanding of sound wave properties
  • Familiarity with the formula speed = wavelength x frequency
  • Knowledge of pressure vs. time graphs
  • Basic grasp of wave functions and their characteristics
NEXT STEPS
  • Research how to calculate the period of a wave
  • Learn about the relationship between frequency and wavelength in sound waves
  • Explore the characteristics of pressure vs. time graphs in acoustics
  • Investigate the implications of using different units in wave calculations
USEFUL FOR

Students and professionals in physics, acoustics researchers, and anyone interested in analyzing sound wave properties through graphical representations.

1. What is the frequency and wavelength of the sound wave that produced the graph?



2. How would you find the wavelength of the graph?



3. I used speed = wavelength x frequency, changed it into frequency = speed / wavelength, used 343 m/s as the speed. I'm just stuck on how to get the wavelength. The units used in the graph are pascals and seconds.

Welcome to PF.

Does the graph resemble a sine or cosine function? Try finding the period, from that you can calculate the frequency.
 
It's a wavelength graph. No sine or cosine functions, no triangles.
