Waves with a frequency of 2.0 hertz are generated along a string The waves have a wavelength of 0.50 meters The speed of the waves along the string is
Definition1/11

v=f*wavelength v=2*.5 v=1 m/s

Term1/11
The speed of sound is approximately 340 ms If a sound wave has a wavelength of 0.68 meters the frequency will be approximately
Definition1/11

No, the speed of sound may be 340 meters per second.

The frequency is speed of sound divided by wavelength.

So your frequency f = 340 / 0.68 = 500 Hz.

No, the speed of sound may be 340 meters per second.

The frequency is speed of sound divided by wavelength.

So your frequency f = 340 / 0.68 = 500 Hz.
