Unformatted text preview: 43. Since the beat frequency equals the difference between the frequencies of the two tuning forks, the frequency of the first fork is either 381 Hz or 387 Hz. When mass is added to this fork its frequency √ decreases (recall, for example, that the frequency of a mass-spring oscillator is proportional to 1/ m). Since the beat frequency also decreases the frequency of the first fork must be greater than the frequency of the second. It must be 387 Hz. ...
