उत्तर
We have to find the wavelength of the sound wave.
Given: Frequency f = 512 Hz
Velocity of sound wave ν = 340 m/s
We know the relation between velocity, frequency, and wavelength `lambda = v/f `,
where ν is the velocity, f the frequency, and λ the wavelength.
So,
`lambda = 340/512` m
= 0.664 m
Therefore, wavelength of the sound wave is 0.66 m.
