Frequency n=5.4 per minute =(5.4/60) Hz Velocity v=n λ =(5.4/60) × 10=0.9 m / s

Q. What will be the wave velocity, if the radar gives $5.4$ waves per minute and wavelength of the given wave is $10 m$ ?

4 m/s

6 m/s

0.9 m/s

5 m/s

Frequency $n = 5.4$ per minute
$= \frac{5.4}{60} Hz$
Velocity $v = nλ$
$= \frac{5.4}{60} \times 10 = 0.9 m / s$
