Amazing Lecture Sir ❤❤
Amazing lecture sir ❤️❤️
Sir all the ray diagrams of concave mirror ☺☺☺😊 i solved....
Thanks so much sir for this lecture bcz i am confuse in this but now I'm crystal clear 👍👍👍👍👍👍👍
सर जब आप पढ़ते हैं तो मजा आता है और एकदम अच्छे से समाज अता है ❤
Concave mirrors
Edit
A concave mirror diagram showing the focus, focal length, centre of curvature, principal axis, etc.
A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the object and the mirror.
The mirrors are called "converging mirrors" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus. This is because the light is reflected at different angles at different spots on the mirror as the normal to the mirror surface differs at each spot.
Uses of concave mirrors
Edit
Concave mirrors are used in reflecting telescopes.[5] They are also used to provide a magnified image of the face for applying make-up or shaving.[6] In illumination applications, concave mirrors are used to gather light from a small source and direct it outward in a beam as in torches, headlamps and spotlights, or to collect light from a large area and focus it into a small spot, as in concentrated solar power. Concave mirrors are used to form optical cavities, which are important in laser construction. Some dental mirrors use a concave surface to provide a magnified image. The mirror landing aid system of modern aircraft carriers also uses a concave mirror.
Doubts:
Why should the aperture be smaller than the radius of curvature?
And does C=2f also apply to lenses?
Best education platform
why the angle of incidence and angle of reflection measured with reference to the normal?
Sir in rjukan town they used concave or convex mirror
Uday hikre👌🏻👌🏻👌🏻
Hi Sir 👌🏻👌🏻🙏🙏
The image of an object which is placed at an infinite distance will be formed at the focus in case of convex and concave mirrors whereas, it is equal to infinity in the case of plane mirror.
Sir please send the notes pdf on telegram
Very imp 41:43
How spoon concave side can make a real image without a screen sir in spoon
sir my doubt is , can principal focus lie only between centre of curvature and pole and not anywhere at principal axis??
It's an aproximation that f=r/2, by the way it's not true
1:26
40:22 imp
if the image is parallel and also passing through the center of curvature, toh kya hoga?
45:36 Samajh nahi aya
If we keep a concave mirror in front of the sun (infinite), are we going to get magnifief image? how big is it going to be??
Doubt:-What happens if the vaccum have particles?
Can someone tell which pencil sir was using as it is drawing good diagrams if you know then plz let us know 🤔
Sir , which is the mirror used in telescope?
Concave Mirror
It is a concave mirror because it has the only case where the image is virtual, erect and enlarged
Thank you ☺️
Sir send notes pdf on telegram
Hi sir
Minimum Light Right Will Be Infinte ????
Sir why covex mirror always show erect and virtual image
Bye
