    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.
