Homework Help: Time & Wavelength?

  1. Sep 7, 2010 #1
    Hi,

    "Somebody makes a noise with a frequency of 1000Hz. Calculate how long it will take to reach somebody 3m away. What will be the wavelength?"

    I can't figure out how it fits into any of the formulas I have!


    Thanks! :)

    What formulas do you have?

    What's the speed of sound?
    How are frequency and wavelength related?

    basically just the universal wave equation. the speed of sound is 340m/s.

    Good. That's all you need to solve this problem.
