Wavelength = 170 mm = 170*10^-3 metres
Velocity of sound = 340 m/s
Frequency = Velocity of sound / Wavelength
= 340 / 170 *10^-3 = 2000 per second = 2000 Hertz
Velocity of sound = 340 m/s
Frequency = Velocity of sound / Wavelength
= 340 / 170 *10^-3 = 2000 per second = 2000 Hertz

v=wavelength×frequency
340m/s=170×f
340÷170=f
f=2
340m/s=170×f
340÷170=f
f=2
