Question

A progressive wave is given by the wave equation $y=Asin(\omega t-kx)$. The direction of the wave is

• A. along +X axis
• B. along -X axis
• C. along -Y axis
• D. along +Y axis

Answer 1

The correct option is A along +X axis

if the wave is moving along positive x axis, then the equation is $(\omega t-kx)$
The correct option is (a)
