A sound wave travelling along an air column of a pipe gets reflected at the open end of the pipe. What is the phase difference between the incident and reflected waves at the open end?

At the open end of organ pipe

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 :-

A strain of sound waves is propagated along an organ pipe and gets reflected from an open end . If the displacement amplitude of the waves (incident and reflected) are 0.002 cm , the frequency is 1000 Hz and wavelength is 40 cm . Then , the displacement amplitude of vibration at a point at distance 10 cm from the open end , inside the pipe is

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:

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

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.

When light suffers reflection at the interface between water and glass, the change of phase in the reflected wave is

The fundamental frequency of an air column in a pipe closed at one end is 100 Hz. If the same pipe is open at both the ends, the frequencies produced in Hz are
