Chapter 31, Problem 8A

To determine

To Explain: The cause of formation of light fringes in the Young’s experiment.

Answer to Problem 8A

In the Young’s experiment, fringes are produced due to the interference in which the light waves from both holes arriving crest to crest.

Explanation of Solution

Introduction:

The phenomena of superimposition of two waves that forms a resultant wave with lower or greater amplitude is called interference.

Thomas young discovered that when monochromatic light is passed through the two closely narrow slits, then dark and bright fringes are produced on the screen. In this experiment, fringes are produced due to the interference in which the light waves from both holes arriving crest to crest superimpose.

Conclusion:

The fringes are produced on the screen due to the interference phenomena of the light.
