Question

In a sinusoidal wave, the time required for a particular point to move from maximum displacement to zero displacement is 0.170s. frequency of wave is

Answer 1

If T is the time period, then time required for a point to move from maximum displacement is zero displacement is T/4.

according to the question,

                             T/4 = 0.170

                                T = 0.170 * 4

                                T = 0.680

we know that time period, T = 1/n   ( n = frequency )

                             therefore, 0.680 = 1/n

                                                  n = 1/0.680

                                                  n = 1.47 Hz

Answer 2

1.47 hz is the answer
