How should two waves superpose each other such that there is (i) constructive interference and (ii) destructive interference.

Answer the following: (a) In Young's double slit experiment, derive the condition for (i) constructive interference and (ii) destructive interference at a point on the screen. (b) A beam of light consisting of two wavelengths, 800 nm and 600 nm is used to obtain the interference fringes in a Young's double slit experiment on a screen placed 1.4 m away. If the two slits are separated by 0.28 mm, calculate the least distance from the central bright maximum where the bright fringes of the two wavelengths coincide.

What is the path difference of destructive interference

State the necessary conditions for the constructive and the destructive interference.

interferences of waves

Which of the following is the path difference for destructive interference ?

State the importance of coherent sources in the phenomenon of interference. In Young's double slit expet-ment to produce interference pattern obtain the conditions for constructive and destructive interference. Hence deduce the expression for the fringe width. How does the firinge width get affected, if the entire experimental apparatus of Young's is immersed in water ?

(i) In Young's double slit experiment the condition for (a) constructive and (b ) destructive interference at a point on the screen .

In the case of light waves from two coherent sources S_(1) and S_(2) , there will be constructive interference at an arbitrary point P, the path difference S_(1)P - S_(2)P is

When a crest and trough of equal implitude and wavelength superpose there is destructive interference. What happens to the energy?

If the intensity of the waves obvserved by two coherent sources is 1. Then the intensity of resultant waves in constructive interferences will be:
