It is clear from the figure that the wavelength λ=0.4 cm . Now v=250 Hz ∴ v=v λ=250 × 0.4=100 cm s -1=1 m s -1

Q. Figure shows the shape of part of a long string in which transverse waves are produced by attaching one end of the string to tuning fork of frequency $250 Hz$ . What is the velocity of the waves?

$1.0 m s^{- 1}$

$1.5 m s^{- 1}$

$2.0 m s^{- 1}$

$2.5 m s^{- 1}$

It is clear from the figure that the wavelength
$λ = 0.4 c m .$ Now $v = 250 Hz$
$∴ v = v λ = 250 \times 0.4 = 100 c m s^{- 1} = 1 m s^{- 1}$
