## Homework Statement

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))

## Homework Equations

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?
