Speed of sound = 330 m/s
Wavelength = 25 cm = 0.25 m
Speed = Wavelength x Frequency
Let the frequency be 'f'
330 = 0.25f
f = 330 ÷ 0.25
f = 1320 Hz
The required answer is Frequency --1320 Hz
Wavelength = 25 cm = 0.25 m
Speed = Wavelength x Frequency
Let the frequency be 'f'
330 = 0.25f
f = 330 ÷ 0.25
f = 1320 Hz
The required answer is Frequency --1320 Hz
