The bestest teacher on KZfaq for lifescience 🤞. Thank you so much sir 😊💖

you are the only person who can help us study without cramming things thanks a lot for your effort for this informative content continue this hardwork

Thank God you teach via you tube. You're such a gem that my entire graduation credit goes to you.

How detailed your explanations are... the concepts are easily understood...keep growing sir..!

Yes! An indian guy always helps me with my Assignments.

Wow Your language is very Easy and the way you teach is incredible. I actually understood every single point in the lecture. Thank you so much

Your lectures let me pass my experimental methods exam, thank you sir. Your explanation is clear, keep the good work.

Well explained! I just ordered my first microscope. Thank you for expanding my knowledge ♥

This was what I was not getting Now it's 💯 % clear

Thank you so much for your video sir. I am messaging from Canada. Your videos provide me relief for a cell biology course im about to take. I have already failed it once and I am retaking it and just seeing and watching your videos provides me a really good idea and makes me more confident. I had this severe anxiety about succeeding in the course and with your videos I feel so much better. I subscribed and Im excited to see you hit 1million soon.

by watching your lectures and getting inspired by u sir I have now opted Bsc biotechnology instead of medical.....now all I am dependent is on ur lectures .... an ideal guru🙏🏻🙏🏻🙏🏻

I am so so proud of you ,you are always great , glad i found you . Thankyou so very much, god bless you ! 💐

Sir, can't explain how much you are helping me during this corona time for self study..🙏

You are the best Teacher sir. You explain me every concepts in very detailed. Thank you so much sir 👍☺️☺️☺️☺️☺️☺️. Best of luck keep going ☺️☺️☺️☺️

You just saved me one more time... I am attending a microscopy course where the professor is not always clear, especially for someone who doesn't a have a good enough physics background like me. After watching this, I have the basics to proceed and actually comprehensively follow the lectures. Thanks a lot, you really are a life saver for so many people around the world :)

Thank you so much!! Your video is super helpful. I learned to understand this concept now for my Microbiology class.

Excellent.thank u brother for giving such easy explanation.

He is the best teacher... Thank you so much Sir for your helful videos 🤗🤗

Sir it's really helpful to understand the microscope thanks for guid us

you said smaller the d, greater the resolution? but according to the diagram of two dots on board, as d decreases, resolution also decreases towards right side, and as d increases towards left side, resolution also increases.. please explain?

God bless u❤..i have no other words... Best concepts delivered... Appreciatable❤

1st to last your lectures always help me.. Thank you so much sir for your clear explanation ☺️

U are the best teacher sir👍💯🥰👏 u are my best teacher on KZfaq channel really 👏

Is area se bhut sare question aate h CSIR net me..clear ho gya formula ab.thank u sir for making so simple..

you are a smart man and a great teacher.thanks

Well explained sir thank you

Sir thank you for your lecture most understandable and informative

you are the best thanks sir

Best explanation ❤

Thank you so much sir ☺️☺️☺️

you are the best thank you

Nice explanation.!

Thank you 😍❤

Best thing is that u used to read all the comments nd try to answer all the comments ❤️😁

Omg next morning I hve exam on this topic 🤩🤩👌

Thank you Sir..😊

Sir BHT Sundar samjhaya h apne ... Agar notes bhi mil jate to sone pe suhaga ho jata

I am a msc student and your videos are more helpful for me

Sir, you are awesome 😇😇

Wow Bravo Mr 🔥

Thank you so much dear sir... For such good explanation ❤️❤️❤️❤️❤️❤️

Got to your video from link mentioned in Kaunas University of Technollogy lecture slide. Proud to see Inndians recognised in Foreign universities as well. Good job bro.

thank you sir aapke video se mujhe graduation me bahut help hua h thank you so much again 🥰🥰🥰🙏🙏🙏🙏

Sir u mentioned that resolution is the ability to see two points seperately.. Then u mentioned d is inversely proportional to resolution..that means the closer the points are the better is the resolution(ability to see two points seperately) Is it that.. resolution is the ability to see two points seperately without missing it's finer details??

Exactly this thing came in my exam yesterday 😅 Still ur video would be helpful for future

Hello, I have question that what is answer of Various sources of illumination used in light microscopes ??

Great video sir, it's really helpful. Can u make a video on how to prepare ARS NET in Agriculture Biotechnology? I know you are the only one to sort out and make a video on it ...........please sir

thnx sir ap nai meri bohat bari mushkil assan kr di ap ko andaza hi nahi hoga u saved my 75 marks

best explanation ever

thank you sir...🙏

Very good explanation 👍

Thank you sir

What was d? The distance between eye piece and object or the distance between objective lens and object?

its very helpful for us i get many information about the microscopy thanks keep it up👍

great explainer :)

Thankyou so much sir

Good job sir

Wow! Well explained thanks

You are Really good

Fabulous man

1st viewer.....tnku Sir ji......

Thanks sir aap bhaut acha pdhate h

Good job

Really Sir...so clearly explained...I'm just spellbound...target to complete watch this lecture series very soon...Thank you Sir

This is a really great channel! I just subscribed. Could you also explain RICM ?

Thank you for the great video! I would like to ask what I should use as lambda in the formel for the limit resolution by epiflurescence. d=0,61.lambda/ NA What is lambda by epiflurescence: excitatationwavelenght or emissionwavelengt?

Sir, does the overall 'd' represent the distance between the sample slide and the objective?

Very very helpful

Sir, how to calculate highest resolution expected from a bright field microscope?

Hello sir! I have a doubt...u said, higher the angle...higher will be the resolution and on the same time, higher the refractive index... higher will be the resolution. Right? But u also said, higher the refractive index, lesser will be the angle...eg. In case of oil...refractive index is 1.51 which is higher than air and water... it's angle will be less...then, it's resolution will be high! But how's it possible? It declines ur 1st statement that higher the angle, higher will be the resolution....! Kindly clear my doubt and thanks a lot for such an amazing explanation of this topic🙏🏻

COOL! new haircut!

I have a doubt sir ,you say resolution is increases when we decrease 'd' ( distance between two points ) but sir if we decrease the distance between two points then points came near and nothing will be visible ,then how can we differentiate between two points Please reply me sir 🙏i am confused

You are my hero

Thanking you sir

Tq so much Sir 🙏🙏

In some questions there is given; value of 2 theta= 90° ..If we want calculate the value of resolving power..should I use the value theta or 2theta?

Thnk you sir combo pack ❤

Can u tell me a idea how i will get a good technical knowledge ? For example i saw your video , i took notes also but is that information is enough for getting deapth knowledge ? Or i can read more related to that topics?

Sir ur grat sir plz answer me If we use an oil immersion objective with blue light for sample illumination then wt will be the resolving power?

What is the significance of magnification written on Objective lens (4X, 100X etc.) ? Every source says that magnification of Objective multiplied by magnification of eyepiece is total magnification. But what exactly magnification of objective lens does?

What should we take wavelength of white colour if it is being used as source ?

Which objective is better at the same magnification : having aperture of 0.34 or 0.87 ?
