**Question**

**If the frequency of a sound wave is 250 Hz and the wavelength is 1.32 m then what is the velocity of the wave? [Ans. 330 m/s] **

**Answer**

The velocity of a wave can be calculated by multiplying the frequency and the wavelength. In this case, the frequency is 250 Hz and the wavelength is 1.32 m.

Velocity = Frequency × Wavelength

Velocity = 250 Hz × 1.32 m

Velocity = 330 m/s

Therefore, the velocity of the wave is 330 m/s.
