    The question is: A tuning fork vibrates at 140 [Hz] and the wave emitted by it propagates with a speed of 340 m / s. Considering the above, it can be correctly stated that the wavelength of the wave emitted by the tuning fork is

    Answer: Wavelength of the wave emitted by the tuning fork is 2.43 m.

    Explanation:

    Given: Frequency = 140 Hz

    Speed = 340 m/s

    wavelength = ?

    Formula used to calculate the wavelength is as follows.

    \lambda = \frac{v}{f}

    where,

    \lambda = wavelength

    v = speed

    f = frequency

    Substitute the values into above formula.

    \lambda = \frac{v}{f}\\= \frac{340 m/s}{140 Hz} (1 Hz = 1 s^{-1})\\= 2.43 m

    Thus, we can conclude that wavelength of the wave emitted by the tuning fork is 2.43 m.
