Question #147182

Middle C on a piano has a frequency of 256 Hz. If the speed of sound in air is 343 m/s, what is the wave’s period?

Expert's answer

We can find the period of the wave from the formula:

"f=\\dfrac{1}{T},""T=\\dfrac{1}{f}=\\dfrac{1}{256\\ Hz}=3.9\\cdot10^{-3}\\ s."

Answer:

"T=3.9\\cdot10^{-3}\\ s."
