A wave has a wavelength of 0.5 meters and a frequency of
120hz.how long would it take for this wave to travel 300 meters.
Neat problem !
If we want to know how long it would take to cover some distance,
we'll need to know its speed.
Wave speed = (wavelength) x (frequency)
= (0.5 m) x (120 / sec)
= 60 m/s .
Then ...
Time = (distance) / (speed)
= (300 m) / (60 m/s)
= 5 seconds .
