neither is the case since diffraction involves the bending of waves upon contact or lack thereof of a physical boundary.
a double slit experiment works on the basis of diffraction and also forms a distinctive interference pattern so in this case the two are related and the diffraction causes the interference but isn't necessarily a case of interference.
A rectangle, and as a special case, a square.A rectangle, and as a special case, a square.A rectangle, and as a special case, a square.A rectangle, and as a special case, a square.
A square is a special case of a rectangle which in turn is a special case of a parallelogram
yes,because in fresnel biprism the fringe width can be increased so that the dark and bright fringes can be seen clearly by naked eyes..but there is no such problem in fresnel biprism.. in young's double slit experiment, the pattern is the superposition of interference and diffraction. but in fresnel biprism it is purely interference pattern.
A kite, a rhombus (special case of a kite), a square (a special case of rhombus).
A rhombus is a special case of a parallelogram where all side are the same length.
It is used by diffraction
none of the above
Yes.
Diffraction is the bending of waves around an obstacle, while interference is the meeting of two waves. For instance, diffraction is what results from a pinhole blocking a wave source, the wave spreads out from that one point. This effect is what creates shadows, regions where the light source is blocked but it is not completely dark. Interference, however, results from two waves colliding with one another undergoing constructive and destructive interference, as in two chords being played. I think the confusion concerning these two different phenomena is the fact that two pinholes, two diffraction sources, results in interference of two sources, which is what the diffraction grating is, which creates the characteristic bands of light and dark interference patterns.
Interference, diffraction.
Interference, diffraction.
yes
Interference.
The Photoelectric Effect and the Compton effect, both of these effects are explained by Photons.

Diffraction phenomenon is broadly classified into two categories: (a) Fresnel diffraction (near-field diffraction) The interference is considered to take place from different parts of an aperture when either the source or screen or both are at finite distance from the obstacle.(b) Fraunhoffer diffraction (far-field diffraction) The interference is considered to take place from different parts of an aperture when either the source or screen or both are at finite distance from the obstacle.== ==
INTERFERENCE IS THE MODIFICATION IN THE DISRIBUTION OF LIGHT DUE TO THE SUPERPOSITION OF TWO OR MORE LIGHT WAVES DIFFRACTION IS THE BENDING OF LIGHT WAVES ACROSS THE EDGES OF AN OBSTACLE AND THEIR ENCROACHMENT INTO THEIR GEOMETRICAL SHADOW
