उत्तर
We have to find the wavelength of the sound wave. We have frequency and velocity of sound wave.
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 = 340/1020` m
= 0.33 m
Therefore, wavelength of the sound wave is 33.3 cm.
