Please help my son year 12 physics -- frequency and wavelength

Click For Summary
SUMMARY

The discussion focuses on calculating wavelength from frequency, specifically using a frequency of 93.4 Hz. The key relationship established is that wavelength can be determined using the formula: wavelength = speed / frequency. It is emphasized that the speed of the wave is dependent on the medium through which it propagates, such as sound in air or light in air. Understanding this relationship is crucial for solving the problem presented.

PREREQUISITES
  • Understanding of wave properties, specifically frequency and wavelength.
  • Familiarity with the formula relating speed, frequency, and wavelength.
  • Knowledge of the speed of sound in air or the speed of light in air.
  • Basic skills in using online resources for research.
NEXT STEPS
  • Research the speed of sound in various mediums, such as air and water.
  • Learn how to apply the formula wavelength = speed / frequency in practical scenarios.
  • Explore the differences in wave behavior between sound waves and electromagnetic waves.
  • Investigate how to calculate wavelength for different frequencies beyond 93.4 Hz.
USEFUL FOR

Students studying physics, particularly those in Year 12, educators teaching wave mechanics, and parents assisting children with physics homework.

my son is trying to find out how he can find an answer by being shown how to do the working out
he wants to find out what the wavelength is if he only has the hz if he is 93.4 hz how does he find out what the wave lenth is
thanks

Welcome to the PF, Martin.

When you show your son how to use Google to find the relationship between wavelength and frequency, what do you find?

BTW, that relationship will depend on the medium that the waves are propagating in. Sound in air has a different relationship versus light in air... :smile:

You need to know the speed of the wave as well. (frequency*wavelength)=speed.
