Microscopic images ,the lenses and issues that confuse students and teachers

Hunting hydra in natural Habitat

:sparkles:Ryle, a student from Royal College Mumbai, is currently searching for hydra in a nearby pond called Krishna Garden Pond in Mumbai. @Ryle

:sparkles:Ryle collected submerged leaves from the pond and suspects that these leaves may contain hydra.

:sparkles:Ryle later transferred the collected water samples into two plastic boxes and examined them under a lens he had at home.

Microscopy in Homelab

:sparkles:According to Ryle, the lens he had was a biconcave lens..Initially Most of us thought it may be Concave lens :orangutan:

Are they !!! @shalinisharma98 @Shraddha276 @dhanraj7

Which lenses that there in Light Compound Microscope !!!

:sparkles:How actually Light Compound Microscope works !!!

Highlighted words during discussions "Iam not Good in Physics ,i am not remembering "

We are in the right place. Let’s discuss and clarify things.

:sparkles:How are images formed in a microscope, and what are the special characteristics of these images?

:sparkles:A compound light microscope consists of two convex lenses.

:sparkles:When light passes through the objective lens, it bends and converges at a point to form a real image. This image is then further magnified, becoming virtual and inverted as it passes through additional lenses.

:sparkles:While these two sentences make it sound simple, representing this concept visually required collaborative effort, with Cubists working together to create diagrams. @Chitralekha @Charvi @Shraddha276 @shalinisharma98

So if that is the case which lens may ryle used to search for hydra !? @shalinisharma98 @Ryle

How can we gain a clearer understanding of lens functions?

:sparkles: And in what situations do we utilize concave (diverging) and convex (converging) lenses?
Can we lists. @Abhi0703 @Shraddha276 @Chitralekha @Arunan & others

Yes, initially @Ryle mistakenly said that the lens he used was biconcave. However, when discussion continued we came to know about the properties of concave and convex lens as diverging and converging respectively. So, if we want to see anything in its enlarged form we need to use convex lens and not the concave. Hence, this convex lens is used in the microscope as well to magnify the image.

Convex lenses are used in the construction of microscopes and telescopes and to correct hypermetropia eye defect.
Concave lenses are used to correct myopia and sometimes in the construction of telescopes.
