The formula to calculate the frequency is:
π =π£*π
f=Ξ»*v
where
π£ is the speed of sound and
π is the wavelength.
Given:
π£ = 343 m/s
π = 44 cm = 0.44 m
Ξ»=44cm=0.44m
Plugging in the values:
π = 343 / 0.44 β 779.55 Hz
The period of a wave is the reciprocal of the frequency:
π = 1/π
T= 1/779.55Hz β 0.00128s(or 1.28 ms)
