1. Homework Statement [/B]
The displacement y of standing wave that is obtained by a superposition of waves :
Y1 = 3 sin (2##\pi##(0.5t - 0 25 x))
Y2 = 3 sin (2##\pi##(0.5t + 0 25 x))
Formula for standing waves
Y = 2Asinkx coswt
The Attempt at a Solution
Y1 going to right
Y2 going to left
Both have different direction.
How to decide it is constructive or destructive interference?
Are they longitudinal or transverse waves? Does it matter?
How to know in the new equation, which belong to sin x or t variable, which belong to cos?
