ICSE Class 9 Answered
A source of wave produces 40 crests and 40 troughs in 0.4 s.What is the frequency of the wave?
Asked by anilrktnayak | 27 Dec, 2019, 04:51: PM
Expert Answer
We know that one crest and one trough makes one cycle.
So here 40 cycles are involved as per the given statement.
Time period = 0.4/40 = 0.01 seconds.
Frequency = 1/T = 1/0.01 = 100 Hz.
