Question

What is phase in wave equation?

Answer 1

Answer:

The Phase:

The phase of the wave is the quantity inside the brackets of the sin-function, and it is an angle measured either in degrees or radians. The important result here is that the two waves can be: (1) In phase if x2−x1=nλ, i.e the wave is doing exactly the same thing at such points along the x-axis.
