A tuning fork of frequency 512 Hz makes 4 beats/s with the vibrating string of a piano. The beat frequency decreases to 2 beats/s when the tension in the piano string is slightly increased.The frequency of the piano string before increasing the tension was (n + 1). They superimpose to give beats. The number of [...]
