difference between interferance nd diffraction of light any 5?
Answers
Answer:
1: Interference is due to the interaction of light coming from two different wavefronts originating from the same source.
1:Diffraction is due to interaction of light coming from different parts of the same wavefront. 2:Interference fringes are of the same width. 2:Diffraction fringes are not of the same width.
3: Interference occur due to interaction between primary wavefronts originating from two coherent sources .
3: diffraction is the result of interaction between two secondary wavelets originating from two different points of same wavefront.
4:interference is a phenomenon in which two waves superimpose to form a resultant wave of greater or lower amplitude.
4:diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings.
5: example, the closely spaced tracks on a CD or DVD act as adiffraction grating to form the familiar rainbow pattern seen when looking at a disc.
5:examples of interference is demonstrated by the light reflected from a film of oil floating on water. Another example is the thin film of a soap bubble, which reflects a spectrum of beautiful colors when illuminated by natural or artificial light sources.
