Answer: 1500 m/sec. ( b )

Solution:

V= f (λ)

Speed = frequency. Wavelength

And frequency = 1/time period

First we will find the frequency :

Frequency = 1/time period

1/0.006 = 166.67 Hz

Using this in the equation:

Speed = frequency. Wavelength

V= f (λ)

9 × 166.67

= 1500.03 ≈ 1500

V (Speed) = 1500 m/s.
