Question

One complete wave passes a putrefying pile of poached pickerel in 0.50 seconds. The piled pickerel protrude 20 cm along the beach. Calculate its frequency.

Answer 1

Since one complete wave passes in 0.50 seconds, it means the period T is equal to 0.50 seconds.

T = 0.5

Frequency, F = 1/T = 1/0.5 = 2 Hz.
