The given information in the question is :
Frequency = 170 Hz
1 Hz = [tex] \frac{1}{s} [/tex]
Frequency = 170 [tex] \frac{1}{s} [/tex]
Wavelength given = 2 m
Speed is unknown which we need to calculate.
Speed can be calculated by using the formula : Speed = wavelength X frequency
By plugging the value of wavelength and frequency in the above formula we get :
Speed = [tex](2m)\times (170\frac{1}{s})[/tex]
Speed = 340[tex]\frac{m}{s}[/tex]
