Answer:
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.
