Question

whats the difference among

convex lens, telescope, and optical microscope

working principle wise

Answer 1

This is my unprofessional analysis.

A convex lens is one piece that is shaped like a center piece of a bulging disk - like flying saucer shape - that will allow some light to pass through it while changing it's direction (of propagation).

Answer 2

Actually, I worded that really badly. It changes the direction of light as it passes from one substance to another.

Answer 3

Optic microscopes and telescopes can use different lenses to bend light to recreate an image to a different scale. Both devices are made for the purpose of ceating an image in a greater scale, but sometimes I turn telescopes around because it's funny to see everything tiny!

Answer 4

I'm not completely sure if what I said about optic microscopes and telescopes is correct.

Answer 5

ah it makes sense :) so basically all these use lenses to magnify ? basic concept is same in all these.. ?
could u plz tell hw bending light scales the image..

Answer 6

http://images.tutorvista.com/content/optical-instruments/compound-microscope.jpeg - that's a confusing picture of a microscope!

Answer 7

And telescopes generally don't make the image bigger than the real thing, but they do make it bigger tha you see otherwise.
