What is the phase difference between two successive crests in the wave

A transverse harmonic wave on a string is decribed by y(x,t) = 3.0 sin (36 t + 0.018x + pi//4) Where x and y are in cm and t in s . The positive direction of x is from left to right. (a) Is this a travelling wave or a stationary wave ? If it is travelling, what are the speed and direction of its propagation ? (b) What are its amplitude and frequency ? (c) What is the initial phase at the starting point ? What is the least distance between two successive crests in the wave ?

What is the phase difference between any two points on a spherical wavefront?

Assertion: Three waves of equal amplitudes interfere at a point. Phase difference between two successive waves is pi/2 . Then, resultant intensity is same as the intensity due to individual wave. Reason: Two different light sources are never coherent.

Distance between two consecutive crests is
