Wave functon of two particles are given by $y_{1} = a\sin(\omega t -kx)$, $y_{2} = a\sin(kx + \omega t)$ , then Option 1) They are moving in opposite direction Option 2) Phase difference between them is $90\degree$ Option 3) Phase difference between them is $180\degree$ Option 4) Phase difference between them is $0\degree$

V Vakul

Both waves are moving opposite to each other.

Wave function -

Function which can mathematically represent a moving wave pulse are called wave function.

- wherein

$y\left ( x,t \right )= f\left ( x\pm vt \right )$

Option 1)

They are moving in opposite direction

This is correct.

Option 2)

Phase difference between them is $90\degree$

This is incorrect.

Option 3)

Phase difference between them is $180\degree$

This is incorrect.

Option 4)

Phase difference between them is $0\degree$

This is incorrect.
