Please explain me the difference between superposition and interference
Asked by Alekhya K | 1st Jul, 2014, 06:43: PM
Expert Answer:
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.

- coherent sources
- two coherent lights with of intensity 5 into 10 to power per to permit your each superimpose and produce the interference pattern on a screen at a point where the path difference between the wave is Lambda divided by 6 where Lambda is the wavelength of the wave find the first phase difference between wave second resultant intensity at the point
- 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?
