Please explain me the difference between superposition and interference
Asked by Alekhya K | 1st Jul, 2014, 06:43: PM
Interference is the result of superposition of two waves.
In simple terms superposition describes the overlapping of two waves.
When two or more wave trains of light travelling in a medium superimpose(overlap) upon each other , then the resultant displacement at any instant is given by the sum of the displacement due to individual waves.This results in interference.
Thus we can say that interference is the phenomenon of re-distribution of energy in a medium on account of superposition of light waves from two coherent light sources.

- We for equal wave intensities the intensity at a point is given by but where does the formula come from??
- Question 15
- kindly answer
- kindly provide answer pl
- In young double slit experiment, slit with ratio is 3:2 then find out the ratio of the maximum and minimum intensity of interference of light.
- How is phase difference related to path difference?
- In Young's double slit experiment, the distance between the slit is kept smaller than the wavelength of the light. What is the effect?
- Why is Interference pattern not detected when the two coherent sources are far apart?
- The phase difference between two light waves emerging from the slits of Young’s experiment is radians. Will the central fringe be bright or dark?
- What will be the effect on the interference fringes obtained in Young's double slit experiment if the monochromatic light is replaced by white light source?
