The ripples in a certain groove 12.7 cm from the center of a 33-rpm phonograph record have a wavelength of 1.75 mm. What will be the frequency of the sound emitted?
1 answer
The frequency of the sound emitted can be calculated using the equation f = v/λ, where f is the frequency, v is the velocity of the wave, and λ is the wavelength. The velocity of sound in air is approximately 343 m/s. Therefore, the frequency of the sound emitted is 343 m/s / 1.75 mm = 196,000 Hz.
