I am unsure about a concept you've covert in this tutorial. At 1:20, we can see the two condenser lenses side by side (the zoomed-in version on the right and the original drawing to the left). The light beam leaving the condenser lens on the original drawing was shown to be divergent as it reaches the specimen. On the RHS drawing, the light beam leaving the condenser lens is shown to be convergent. Which one of these is the correct behavior of a condenser lens? Thanks.
Good work. A little digging into why only "Sine of half angle" and how this angle is increased with lens having shorter working distance would have really helped the viewer.
so... the numerical aperture calculates whether the beam (cone) of light will be fully received within the diameter of the maximum objective lens? If this is the correct way of thinking, why does physics say the maximum objective lens cannot be increased?
Yes my friend.... but if the signal is low then lowering pinhole size increase the resolution in cost of sognal because less light can pass through... so always there is a trade off and fine balance
your "abbibibiliti" was very good take it as a comliment
This video is really great. You turned a really complicated subject for me into something that was easy to understand! Thank you so much!!

DeafMusicians The right hand side is more correct.

Hmm. Thanks for your feedback. This video is old . I will make a new video on this
Super informative! Thanks a bunch!
Kristoffer Nyqvist glad it helped........share among friends...happy learning

Thanks
Your video helped me to understand the concept
Good video, thanks!
Very nice keep it up the good work
Please share
You’re drawing is great you should keep doing this
Please share among friends and help me to reach big audience
What camera had you been used to record this video please? thank you!
It was a prehistoric nokia lumia phone camera with horrible video quality
@@animatedbiologywitharpan so you have a long journey from nokia phone to the outstanding powerpoint design. Congrats!
@@bacsidon yup thats true
Thanks for your information sir

Nice video, short and informative
Soon my microscopy playlist will be restructured..... stay tuned... please share among your friends and help me to reach big audience
Amazing

Your thought process is correct
Clear explanation.
Glad it was helpful!
Thanks a lot
very good video for understand the N.A

Thank you so much
Does wavelength effect on NA?how
NA is a feature of lens and it depends on RI of media but not the wavelength of light.
Tq
does decrease in the pinhole size increase resolution?
Yes my friend.... but if the signal is low then lowering pinhole size increase the resolution in cost of sognal because less light can pass through... so always there is a trade off and fine balance
Please watch this video for detailsua-cam.com/video/FJbn_eXzA4o/v-deo.html
Does the magnification depends on this ??
mr. biology magnification is the function of lens curvature it does not depend on NA......but the other way round is true
@@animatedbiologywitharpan thanks you
Bhai,hindi me video banate toh hum jaise students ki bhi help ho jati...
Problem kya hain hindi se?
Sbko samjh ata hindi me vdo hoti toh
the problem is i can't speak Hindi that well.....still i would give it a try
