Waves `y_(1)=Acos(0.5pix-100pit)andy_(2)=Acos(0.46pix-92pit)` are travelling along the x-axis. (here x is in metre and t is in second)
Q. Find the number of times intensity is maximum in time interval of 1 s.

A

100

B

46

C

192

D

96

Text Solution

Verified by Experts

The correct Answer is:
A
At `x=0,y=y_1+y_2`
`y=2A cos 96 pit cos4 pit`
It will be When either function are zero `implies n le 96 or m le4 implies n+m=100`
