Sagot :
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.
[tex]\lambda = \frac{v}{f}[/tex]
where,
[tex]\lambda[/tex] = wavelength
v = speed
f = frequency
Substitute the values into above formula.
[tex]\lambda = \frac{v}{f}\\= \frac{340 m/s}{140 Hz} (1 Hz = 1 s^{-1})\\= 2.43 m[/tex]
Thus, we can conclude that wavelength of the wave emitted by the tuning fork is 2.43 m.
