The initial phase difference between two coherent waves is`pi` . What type of fringe occur at centre of the screen in YDSE.

Between two coherent waves phase is:

If the path difference between the interfering waves is n lambda , then the fringes obtained on the screen will be

The phase difference between two particies executing shm is pi//2 . What does it mean?

The average path difference between two waves coming from third and fifth fresnel zones of a wave front at the centre of the screen is

In Young.s double slit experiment, what is the path difference between the two light waves forming 5th bright band (fringe) on the screen ?

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 :-

In Young's double slit experiment, the phase difference between the two waves reaching at the location of the third dark fringe is

Interference fringes are produced on a screen by using two light sources of intensities / and 9/. The phase difference between the beams pi/2 is at point P and pi at point Q on the screen. The difference between the resultant intensities at point P and Q is

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.
