Suppose three tuning forks of frequencies 260 Hz, 262 Hz, and 266 Hz are available. What beat frequencies are possible for pairs of these forks sounde?

Two, four, and six Hz are possible beat frequencies for pairs of these tuning forks sounded together.

Explanation:

The number of wobbles per second is called the beat frequency, which can be calculated by taking difference in two individual frequencies of two sound waves.

Thus,

262 Hz - 260 Hz = 2 Hz

266 Hz - 262 Hz = 4 Hz

266 Hz - 260 Hz = 6 Hz

Hence,

Two, four, and six Hz are possible beat frequencies for pairs of these tuning forks sounded together.
