Find the frequency of a wave produced by a genetor that emit

Solution

Time taken for 30 pulses t = 2.5 s

Time taken for one pulse, T = t/30

                                        = 2.5 s/ 30

                                       = 83.33 x10 ^-3 s

Frequency fo the wave f = 1/T

                                   = 1/(83.33 x10 ^-3 )

                                   = 12 Hz
