[@chloe-i3v]

To people confused about the focal length of the concave mirror, I did some research. It's just a convention and either way can work - you just need to be consistent, whichever you choose. From my research, the most used convention is the focal length of a concave mirror is POSITIVE. (same convention with other converging devices such as convex lens) Which I would stick to, since this video went with that convention, and changing things over will cause unnecessary confusion.

The Organic Bro, Let me tell ya , This!!!, YOUR VIDEOS ROCKKK MANNN!!!!!!😆😆😆😎

[@bhairavirajasekar4228]

Hey great video but I noticed a mistake at 13:48. If you have an object placed between f and C, the reflected image will be located beyond C (as in di > 2f). I checked my math with the sample of f=8cm, do = 12 cm, ho = 4 cm. In this situation, I found that C =16 cm and the calculated di = 24 cm so therefore di > C.

[@darkerufo]

NOTES: 1/f = 1/do + 1/di distance (do, di) -positive if it is on the front of the mirror -negatice if it is on the back of the mirror focal length (f) - positive for concave mirrors - negative for convex mirrors M = hi/ho = -di/do - positive, upright image with respect to the object - negative, inverted image with respect to the object - |m| > 1; enlarged image - 0 < |m| < 1; reduced image - |m| = 1; same size

[@nadiacoleman8028]

for the concave mirror example in the beginning was the focal length supposed to be negative? Also around 18:30 you said that the focal length for a convex mirror was negative, but I looked it up and it's positive.

thanks for taking ur time to explain this explicitly to our my understanding thumbs up

[@stupefyore]

5:35 I did this problem but with transposing the 1/24 to the left. and that would be 1/8-1/24=1/di... now 1/8-1/24 is equals to 1/12 so 1/di=1/12 and we just get the reciprocal... di=12 same thing I did with 19:06

[@AmahleMncwabe-g2q]

I did the same thing but then with the 19:06 problem the answers are different when comparing them with his ,I got -6

[@zarithevill]

The 2 incident rays: Obj to mirror to focal ( not parallel to axis plane) Obj to focal to mirror ( parallel to axis plane) Special case (convexed lens) - obj to mirror refract to center whereby center distance to mirror is radius thus focal/focusing point distance to mirror is r/2 Actual converge/intersect is Real i fake converge formed from actual divergence is Virtual image (so to say, diverge on front side && converge back side && image behind mirror)

[@WeddingWhims]

19:00 you said it’s concave mirror but in your calculations you use covex mirror

In your examplat at 5:47, shouldn't 1/24 be negative? when do you use negative vs positive for object distance?

Please I am confused, is the focal length of concave mirror not supposed to be negative and that of convex mirror positive?. I check other sources and they said convex mirror focal length carries positive why that of concave mirror carries negative. Please help.

[@olivedits6222]

According to the Cartesian sign convention the focal length of a concave mirror is always negative while in context of the convex mirror it is positive.
