DETERMINATION OF HE-NE LASER WAVELENGTH BY USING THE M I EXPERIMENT

DETERMINATION OF HE-NE LASER WAVELENGTH BY USING THE M I EXPERIMENT

The two interfering waves construct the interference pattern.

The circular pattern of fringes depends upon the uniform thickness between the two mirrors.

These Viva Questions will help you to understand the experiment.

1Q. Define what is Interference?

when two or more waves meet and combine, resulting in a new wave pattern

2Q. What is the condition for Interference?

The waves must have the same frequency and they must be coherent. Their phase difference must remain constant over time.

3Q. Explain the LASER properties and what do you mean by a Coherent Source?

Coherent,Monochromatic,highly directional, highly intense. waves are all in phase with each other

4Q. Why you are using the LASER source, why not bulb or sunlight, tube light?

It is monochromatic, coherent and highly directional.

5Q. Why do you keep compensating plate in the path of the light ray, is it transparent or semi-silvered plate?

To make the the path of both light rays equal, so a constant phase difference. Transparent
