Michelson Interferometer - Part 1 | Construction and find Wavelength | explained in HINDI

In this Physics video lecture for B.Sc. we explained the working and construction of Michelson Interferometer and also discussed on its applications or usages. It is based on the principle of interference due to path difference of two coherent sources. It is very popular due to its simple design.
It is used :
1) To determine wavelength of monochromatic light
2) To find the difference in wavelength between two neighbouring spectral lines
3) To find the refractive index and thickness of a thin transparent material
4) To measure the standard metre in terms of wavelength of light
5) To find the refractive index of a gas
When the knob of the interferometer is rotated one of the mirrors move and hence path difference is created. Due to the path difference interference fringes cross the centre of the interference field on the screen. Counting the crossing of the fringes and the amount the mirror is shifted, we can determine the wavelength of the monochromatic light from the source.

लाजवाब,,,, यही बात ग्राफ़िक्स से बहुत ही अच्छा समझ आया । किताब से समझ नहीं आ रहा था ।
Thanks

In morning ...i am watching the video ...sir aap ki video dekh kar ek physics student ke liye . Ek dum achii vali good morning ho jati hai...thank you sir ..

[@pushprajbhardwaj4820]

Wonderful sir,
Even a class 12th student can understand this.
You have nicely explained this too.

[@Prince-speak]

It's easy to understand with practical.
Because we see it. So our brain make figure and how it is working.

[@sailendrasingh_]

Nice lecture Sir, yesterday HC Verma came my college and he told us about Michelson Interferometer. The given information about it by you is almost similar to HC Verma.

[@psxinformation]

Both he achi video ha.... Both khoob
Sir ap ka method both acha ha samjhany ka...

[@kelashbgehlot3802]

Sir what about the path difference in the slab for the light passed from M1, and change of phase when light reflected on the slab for the light coming from mirror M2 ? We have to consider that also for interference.

[@kaustuvregmi1469]

Wow sir nice video

Sir please Fabry Perot Interferometer ka bhi...

[@cosmicmelody4259]

Sir d ko to nano meter me hona hoga, kuki wavelength nanometer me ha

[@asiaramay6148]

One confusion, why interference pattern is circular while in Michelson interferometer, fringe pattern is not circular but only in newton rings!

[@sukantanayak1887]

Sir why just Michelson...give a description on newtons ring, Lloyd's mirror , fresnels biprism, fringe of equal width and equal inclination

[@VikashKumar-qi6yx]

Bhai Etalon bhi hai

[@vikashentertainmentshows6719]

Sir Doppler effect relativistic theory se banaye na aur iss video ke liye thanks

Hello
You are welcome.
Yes! I shall.
And as always ...... thanks for watching.

[@DikshaSharma-ul7hw]

Thanks sir 😺☺️

[@fatimakhan8050]

Thank u sir 👍👍

[@sagarverma3546]

Sir, how to get circular fringes by michelson interferometer

[@edupoint.physics]

Two mirrors at 90 degrees.

[@sscMEA-zv7of]

Jo light wave pass ho Rahi hai o kon se lense se pass ho Rahi hai sir ji

[@satyaomnarayanswami2826]

But sir without compensating plate there will be an pathdifference between reflected wave and refracted ray
