A tuning fork resonates with the note E. If the soundwave has a wavelength of 82 cm and a wave speed of540 m/s, what is the frequency of the note E?
Question
A tuning fork resonates with the note E. If the soundwave has a wavelength of 82 cm and a wave speed of540 m/s, what is the frequency of the note E?
Solution
The frequency of a wave can be calculated using the formula:
Frequency = Speed / Wavelength
Given that the speed of the wave is 540 m/s and the wavelength is 82 cm (or 0.82 m), we can substitute these values into the formula:
Frequency = 540 m/s / 0.82 m = 658.54 Hz
Therefore, the frequency of the note E in this case is approximately 659 Hz.
