A tuning fork having a frequency of 312 Hz emits a wave which has a wavelength of 1.10 m. Calculate the velocity of sound

A. 312.0 ms−1
B. 110.0 ms−1
C. 343.2 ms−1
D. 686.4 ms−1

Correct Answer:

Option C = 343.2 ms−1

Explanation

v = f λ to calculate the wave’s velocity.

v = 312 x 1.10

= 343.2m/s
