Two pulses are moving along a string. one pulse is moving to the right and the second is moving to the left. both pulses reach point x at the same instant. an illustration of a triangular trough traveling right and the same size and shape crest traveling left both toward point x. they are equidistant from x. will there be an instance in which the wave interference is at the same level as point x? no, the interfering waves will always be above x. no, the interfering waves will always fall below x. yes, the overlap will occur during the slope of the waves. yes, the overlap will occur when the first wave hits point x.

If the waves travel in the same direction, their sum gives resulting waves that can be maximum or minimum depending on the phase between them, un stationary patterns.

If the directions are coincident directions, they add place to the interference processes, in this case, stationary patterns are formed on a screen.

If the waves travel in the opposite direction the sum of the two waves gives rise to a wave that maximum is the sum of the amplitudes of the two pulses

In the case of a pulse that corresponds to a single wavelength, the result is an instantaneous maximum, which after the pulse passes, returns to zero.

Consequently, there is no stationary pattern, so there is no interference between the two pulses.

In conclusion with the sum of the pulses, we can find that the answer is No interference pattern is produced as the amplitude does not remain constant.
