Statement:
A wave has a wavelength of 0.78 m and a speed of 343 m/s.
To find out:
The frequency of the wave.
Solution:
- Wavelength of the wave (λ) = 0.78 m
- Speed (v) = 343 m/s
- Let the frequency of the wave be v (Nu)
- We know the formula, v = v (Nu) × λ
- Putting the values in the above formula, we get
- 343 m/s = v (Nu) × 0.78 m
- or, v (Nu) = 343 m/s ÷ 0.78 m
- or, v (Nu) = 439.74 Hz (approximate value)
- So, the frequency of the wave is 439.74 Hz.
