3Fraunhofer Diffraction: In the case of a very narrow slit and when the viewing screen is at a considerable distance from the slit, the angular position of the first minimum (θ) can be approximated using the equation: sin(θ) = mλ / a, where 'm' is the order of the minimum (usually 1 for the first minimum), λ is the wavelength of light, and 'a' is the width of the slit. Approximation for the First Minimum: For the first minimum (m = 1), sin(θ) is approximately equal to 1.22 times λ / a. This 1.22 factor is a result of more detailed mathematical analysis and is often used as a convenient approximation for practical calculations. So, the number 1.22 arises from the mathematical analysis of diffraction patterns and helps in estimating the angle at which the first minimum occurs in the diffraction pattern of light passing through a narrow slit.
anna is there any chance to postpone cbse 12 exams we feel stressed there is lot to study but time is less, by god grace we finished our practical's but concepts are confusing i am trying out my best but not that much good like my 10th preparation 😥
Good evening sir. I have a doubt. Why can't we see the image of the object which is placed at infinity distance formed by the refracting telescope for long time.
sir antha rain collecting sonigala athula oru doubt ena na same ma na rain level drop erutha small pot and large pot la same leavel water tha collect agum sir 🤔🤔
Sir one small doubt!! Object distance um infinite la iruku, telescope vazhiya paakum pothu image distance um infinite la iruku, then what is the purpose of telescope? nama direct ah paathutu poolame..... ???
Infinity not means that both of tnem r in Infinity distance because in physics Infinity was invalid. Infinity means very long distance compared to the radius of lens. The object was light years away but we saw it's image in near but much much longer than radius of lens. I hope u understand.

Tq for the video ♥️
Bro intha lesson Ray optics la erukku wave optics la illa.
Ithu vera Playlist la save pannathu naala search panni panni kadupu aiten...😪
BTW xplainaition mass ah panringa bro...🤩
Intro mass✌✌
Intro's so good that it could be used for nowadays videos sir...... ❤️
Super teaching sir
Super sir nallave understand akoothu TQ sir evolo clear ra explain panrinka ❤️❤️
Tq so much 😊😊sir romba clear ah puridu ❤❤ keep rocking 🎉🎉
athu L = mod fe to mod fo thaane length because focal length negative aaiyuduchunaa...length decrease aagum??
can we use terrestial telescope as astronomical telescope since process is same
Sir actually your teaching is very understandable and I have a doubt regarding image forming at infinity... In a telescope
Saddest thing that Galileo was illtreated in his final years
Sir one more doubt. 1.22 lambda what is this value and from where we got
I too have the same doubt

anna oru kind request
dont talk too smart(dont take it serious)
neenga epavum pola pesunga naa pls ,we need a friendly manner of teaching
Thank u for ur clear explanation sir...
Can u please teach ncert concepts from physics...please sir...
Group exam pathi sollunga sir
Love you Anna ❤️
anna is there any chance to postpone cbse 12 exams we feel stressed there is lot to study but time is less, by god grace we finished our practical's but concepts are confusing i am trying out my best but not that much good like my 10th preparation 😥
Yes bro, i am also struggling for cbse 12th Board preparation, but now according to present situation they can be further postponing board exam bro
Why can't we use a concave lens as eye piece instead of two lens...
Good evening sir.
I have a doubt. Why can't we see the image of the object which is placed at infinity distance formed by the refracting telescope for long time.
Simple that object is our perspective but throught the telescope its light .so our eyes get more brighter that's y like that.
@@EYEVISIONINDIA2020subscribed 👍
Sir,can we say terrestrial telescope=binocular?
Telescope is field view low but u can magnifying more to change eyepiece but binocular is very less but field of view is more .
Resolving power of a telescope clg question solluga anna
Thank you sir for super teaching
Nuclei atoms most of them are theory only sir for cbse 2023
Yen sir namma astronomical tele layum inverted matha innoru oru lense use panna koodathu?
Easy a understand athuguthu sir thanks sir
❤💚
intro is good
sir antha rain collecting sonigala athula oru doubt ena na same ma na rain level drop erutha small pot and large pot la same leavel water tha collect agum sir 🤔🤔
Illa ..
See size of vessel varies
Trb exam pathi solungala
Sir one small doubt!!

Velammal ?
Anna what is cassegrain telescope
Will you put Videos on chemistry ?
Dheivame!!!!
Super bro
Thalivaaaaa
ana nega iruka varikum exam pahtu bayam illa
Image and object confuse aaguravanga yaaru yaaru????😅😶
Sir, we studied angular magnification in simple microscope not in compound microscope 👍
Sir u r working in government school ha
No
Sir ithu ray optics illaya
It's wave optics
In which lesson 😢😢
