A vibrating tuning fork makes 500 vibrations in one second. What is the wavelength of the sound produced if the air temperature is 20°C? Group of answer choices

0.500 m
0.686 m
0.343 m
1.46 m
1.87 m

Answer :

Answer:

wavelength will be 0.686 m

So option (b) is correct

Explanation:

We have given vibration in one second that is frequency = 500 Hz

We know that velocity of sound is 343 m/sec

We have to find the wavelength

We know that velocity is given by [tex]v=\lambda f[/tex]

So wavelength [tex]\lambda =\frac{v}{f}=\frac{343}{500}=0.686m[/tex]

So wavelength will be 0.686 m

So option (b) is correct
