Question 1 Report

In a sound wave in air, the adjacent rarefactions and compressions are separated by a distance of 17cm. If the velocity of the sound wave is 340ms-1. Determine the frequency

10Hz

20Hz

1000Hz

5780Hz

Answer Details

$λ$ = 2L

2 x 17 = 34cm

F = $\frac{V}{λ}$

= $\frac{340}{34 \times 10^{- 2}}$

= 1000Hz
