Quiz Michelson Interferometer Experiment

1. How one can change the thickness of thin air film?

2. The two light waves in M.I. the experiment that satisfies the interference condition at eyepiece make a form?

3. Where image forms of the M2 mirror by a semi-silvered glass plate?

4. Where thin film of air forms?

5. How the velocity of light changes (once c-v and then c+v), what is the reason for it?

where c is the speed of light and v is the earth’s velocity.

6. How do we observe a reflected and transmitted light beam from a monochromatic source?

7. Which one is fixed mirror M1 or M2 in the Michelson Interferometer experiment?

8. What about compensating plate thickness? is it of the same thickness as semi silvered or varies place to place?

9. What is the condition for colored Interference?

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

11. Why you are using the LASER (monochromatic source) why not bulb or sunlight, tube light?

12. why do we keep a semi silvered glass plate at 45 degrees?

13. At which angle M1 and M2 mirror are fixed?

14. What is the condition to be Coherent Sources?

15. To find the path difference between light rays we use?
