Question on: JAMB Physics - 2022
A tuning fork that has a frequency of 312Hz emits a wave which has a wavelength of 1.10 m. Find 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 Option: C
To find the velocity of sound, we can use the following formula:
velocity (v) = frequency (f) * wavelength (λ)
Given:
* Frequency (f) = 312 Hz
* Wavelength (λ) = 1.10 m
Calculation:
v = 312 Hz * 1.10 m = 343.2 m/s
