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

Correct answer is C

\(\lambda\) = 2L

2 x 17 = 34cm

F = \(\frac{V}{\lambda}\)

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

= 1000Hz
