What is the phase difference between the incident wave and the reflected wave in the following ?
1. Wave reflected from rigid boundary.
2. Wave reflected from free boundary.

What is the phase difference between the displacement wave and pressure wave in sound wave :-

What is the phase difference between the displacement wave and pressure wave in sound wave :-

The change in phase if a wave is reflected from a rigid surface is

When a sky wave is reflected on to the ground

A sound source, detector and a cardboard are arranged as shown in figure. The wave is reflected from the cardboard at the line symmetry of source edetector. Initially the path difference between the reflected wave and the direct wave is one third of the wavelength of sound. Find the minimum distance by which the cardboard should be moved upwards so that both waves are in phase.

A wave is reflected from a rigid support. The change in phase on reflection will be

Draw a diagram to show the shape of a square wave pulse on a string when it gets reflected from (i) fixed boundary and (ii) a free end boundary.

A cylinderical tube, open at one end and closed at the other, is in acoustic unison (resonance) with an external source of sound of singal frequency held at the open end of the tube, in its fundamental note. Then : A. the displacement wave from the source gets reflected with a phase change of pi at the closed end B. the pressrue wave from the source get reflected without a phase change at the closed end C. the wave reflected from the closed and again gets reflected at the open end D. the wave reflected from the closed end does not suffer reflection at the open end

When a sound wave is reflected from a wall the phase difference between the reflected and incident pressure wave is:

When a sound wave is reflected from a wall the phase difference between the reflected and incident pressure wave is:
