**Question**

**The velocity of a wave having wavelength 1.7 m is 340 m/s. Find the frequency of the wave. [Ans. 200 Hz] **

**Answer**

The frequency of a wave can be calculated by dividing the velocity by the wavelength. In this case, the wavelength is 1.7 m and the velocity is 340 m/s.

Frequency = Velocity \over Wavelength

Frequency = 340 × 1.7

Frequency = 200 Hz

Therefore, the frequency of the wave is 200 Hz.
