Homework Statement
Two sinusoidal waves have the same angular frequency, the same amplitude ym, and travel in the same direction in the same medium. If they differ in phase by 50 degrees, the amplitude of the resultant wave is?
Homework Equations
The Attempt at a Solution
How do I go about figuring this out? Do I need to use phasors?
[tex]\sqrt{(1+cos(50))^{2} + (sin(50))^{2}}[/tex]
Isn't the superposition of 2 waves y1(x,t) and y2(x,t)
y'(x,t) = y1(x,t)+y2(x,t)
?
Thanks again!
