Question
Two waves
y1 = Acos(0.5 πx - 100πt) and
y2 = Acos(0.46 πx - 92 πt)
are travelling in a pipe placed along x-axis. Find the number of times intensity is maximum in time interval of 1 sec:-
y1 = Acos(0.5 πx - 100πt) and
y2 = Acos(0.46 πx - 92 πt)
are travelling in a pipe placed along x-axis. Find the number of times intensity is maximum in time interval of 1 sec:-
Options
A.4
B.6
C.8
D.10
Solution
No. of time intensity is maximum in one second
= beat freq.
= n1 - n2
= 4 beats/sec
= 4 times/sec
= beat freq.
= n1 - n2
= 4 beats/sec
= 4 times/sec
