SUMMARY

The frequency of a wave traveling at 44.0 m/s with a maximum displacement of 18.0 cm and a total distance of 28.0 m is calculated to be 2.6 Hz. The wavelength was determined to be 16.8 m based on the corrected count of 6 ticks per wavelength. The formula used for calculating frequency is f = c/λ, where c is the wave speed and λ is the wavelength.

PREREQUISITES
  • Understanding of wave mechanics
  • Familiarity with the formula for frequency (f = c/λ)
  • Knowledge of measuring wavelength in a wave graph
  • Basic arithmetic for calculations
NEXT STEPS
  • Study wave speed calculations in different mediums
  • Learn about the relationship between wavelength and frequency in various wave types
  • Explore the effects of amplitude on wave behavior
  • Investigate advanced wave phenomena such as interference and diffraction
USEFUL FOR

Students studying physics, particularly those focusing on wave mechanics, as well as educators looking for practical examples of wave frequency calculations.

Homework Statement


A snapshot graph of a traveling wave is shown. The wave is traveling to the right at 44.0 m/s. the maximum displacement is 18.0 cm and the total distance traveled by the wave is 28.0 m
What is the frequency?

Homework Equations


The Attempt at a Solution


total distance traveled/ # ticks = 28 m/10 = 2.8m/tick

There are 7 ticks in one wavelength

7*2.8 = 19.6 m

Do a recount. Once you find the wavelength, how do you calculate the frequency?
 
now it works, thanks :)
** 6 ticks to a wavelength, making it 16.8 m

and then frequency = c/lamba
= 44/16.8
= 2.6 Hz
