Answer:
The frequency of of the note = 131 Hz.
Explanation:
Frequency: Frequency can be defined as the number of complete oscillation completed by a wave in one seconds. The S.I unit of frequency is Hertz ( Hz)
v = λf ............................ Equation 1
Making f the subject of the equation,
f = v/λ .......................... Equation 2
Where v = Speed, λ = wavelength, f = frequency
Given: v = 343 m/s, λ = 2.62 m.
Substituting these values into equation 2
f = 343/2.62
f = 131 Hz
Thus the frequency of of the note = 131 Hz.
