The superposing waves are represented by the following equations : y1 = 5 sin 2 π (10t−0.1x), y2 = 10 sin 2 π (10t−0.1x+ϕ) Ratio of intensities ImaxImin will be
a1=5, a2=10 ⇒ ImaxImin=(a1+a2)2(a1−a2)2=(5+105−10)2=91
The superposing waves are represented by the following equations :
y1=5 sin 2π(10t−0.1x), y2=10 sin 2π(20t−0.2x)
Ratio of intensities ImaxImin will be
