Question

Frequency of a vibrating string with a period of 4 seconds ​

Answer 1

Answer: 2 Hz (8 cycles/4 s = 2 cycles/s).

Step-by-step explanation:

If a coil of slinky makes 3 vibrational cycles in one second, then the frequency is 3 Hz. And if a coil makes 8 vibrational cycles in 4 seconds, then the frequency is 2 Hz (8 cycles/4 s = 2 cycles/s).
