Homework Statement
Two superimposing waves are represented by equations
y1= 2sin 2π(10t – 0.4x)
y2= 4sin 2π(20t – 0.8x)
Find the ratio of Imax and Imin. Ans is (25:9)
Homework Equations
The Attempt at a Solution
I know that intensity is proportional to the square of amplitude and
maximum amplitude = a1 + a2
minimum amplitude = a1 - a2
but these equations are only applicable for waves with same frequency. so how do I proceed ? Thanks in advance!
