Vibrations & Waves Challenge #1 — Wave Speed

The wavelength
of a sound.

Vibrations & Waves Easy

Problem

A loudspeaker produces a steady tone with a frequency of 500 Hz. The speed of sound in air is 340 m/s. Calculate the wavelength of the sound wave.

Frequency\( f = 500\ \mathrm{Hz} \)
Speed of sound\( v = 340\ \mathrm{m/s} \)
Answer inmetres

Assume still air at room temperature.

Hint: speed, frequency and wavelength are locked together by one equation: \( v = f\lambda \). You already know two of the three.
