Based on the standard formula and data in the question, the frequency of a sound source that produces the same wavelength in 20∘c air is "<u>115.87Hz</u>."
<h3>What is the frequency of a sound source?</h3>
The <u>frequency of a sound source</u> is the quantity of waves that move through a point per unit of time.
Typically, a sound wave arises from a source vibrating at a frequency f, propagates at v, and has a wavelength λ.
Therefore, in this case, we have
Velocity (v) of sound in air = 343 m/s
Wavelength (λ) = 2.96 m
Frequency (f) =?
f = v ÷ λ
f = 3.43m/s ÷ 2.96m
=> 115.87Hz
Hence, in this case, it is concluded that the correct answer is 115.87Hz.
