SUMMARY

The discussion centers on calculating the wavelength of a dog whistle emitting sound at a frequency of 30,000 Hz. Participants emphasize the necessity of knowing the speed of sound in air, which is approximately 343 meters per second, to utilize the formula wavelength = speed / frequency. The user seeking help confirms that the homework does not provide the speed, leading to confusion about how to proceed with the calculation. The correct wavelength can be determined once the speed of sound is applied in the equation.

PREREQUISITES
  • Understanding of the relationship between frequency and wavelength
  • Knowledge of the speed of sound in air (approximately 343 m/s)
  • Familiarity with basic physics equations
  • Ability to perform unit conversions if necessary
NEXT STEPS
  • Research the speed of sound in different mediums (e.g., air, water, solids)
  • Learn how to calculate wavelength using the formula wavelength = speed / frequency
  • Explore the effects of temperature and pressure on the speed of sound
  • Study the properties of sound waves and their applications in various fields
USEFUL FOR

Students studying physics, educators teaching sound wave properties, and anyone preparing for quizzes or exams related to acoustics and wave mechanics.

Homework Statement


Dogs are able to hear mucher hgher frequencies than humans are capable f detecting. For this reason, dog whistles that are inaudible to the human ear, can be easily heard by a dog. If a dog whistle has a frequency of 30,0000 Hz, what is the wavelength of sound emitted.

Homework Equations





The Attempt at a Solution


Well I was trying to find the wavelength using the equation speed=Hz(Wavelength) but I don't have the speed. So I am really lost. If
anyone could guide me in some helpful equations I might need, because I have a quiz on this tomorrow
 
Physics news on Phys.org
Are you sure the book/exercise you got the question doesn't give you the speed?

Yea positive. Checked it twice that's why I was confused.

Maybe I have to know the speed of sound through Air?
