consider three waves represented by
y1= 3sin(kx- ωt)
y1= 3sin(kx- ωt +2 pie/3)
y1= 3sin(kx- ωt +4pie/3)
what is the amplitude of resultant of waves at x=0?
Just do the vector sum of Wave at x=0 taking wt as reference line.
You'll get A=0
Ya your answer is right, but can you elaborate it plzzzz
2π/3 means 120° and a circle can be divided into three equal parts when angle b/w lines is 2π/3.
