In which way redistribution of energy exists in the interference of light. What are the values of
phase difference and path difference in the positions of constructive interference and destructive
interference? What will be the effect on interference fringes when white light source is used
instead of monochromatic light source in Young's double slit experiment?
Answers
Answer:
When two or more waves travel through a medium and superpose then the resultant intensity do not distributed uniformly in the space .At some places , it is maximum while at some other places it is minimum . This non uniform distribution of intensity or energy of light is known as interference .
The interference of two waves. When in phase, the two lower waves create constructive interference (left), resulting in a wave of greater amplitude. When 180° out of phase, they create destructive interference (right).
In physics, interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude. Constructive and destructive interference result from the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves, gravity waves, or matter waves. The resulting images or graphs are called interferograms.
Explanation:
9. The re distribution of light emitted by two point sources is called a) Diffraction by) Total internal reflection Scattering and) Interference
