Speed, V = 700m/s
Wavelength, λ = 30cm
= 0.35m
Speed of the wave = Wavelength x Frequency
V = λ x v
700m/s = 0.35m x Frequency
Frequency = 700m/s / 0.35m
= 2000Hz
Wavelength, λ = 30cm
= 0.35m
Speed of the wave = Wavelength x Frequency
V = λ x v
700m/s = 0.35m x Frequency
Frequency = 700m/s / 0.35m
= 2000Hz
