The bottom point is actually the HARDEST one to calculate, since you need 2 rays to see where the rays look like they come from. The parallel line to the axis and the one that goes through the focus are the same, so it is in practice the only point of the arrow where this is not trivial.

i have a science exam tomorrow and i didnt look at my notes once....i just watched ur vids and i understand everything perfectly now
thanka!

[@masons2442]

How'd not looking at your notes go?

[@SilencerBlood]

Awesome Way to convey the Concept.. THANKS!!!

I have an exam in less than 4 hours and I only now I have watched this video do I understand concave and convex mirrors.

[@manjuprasannakumar2222]

Thank you... More better than my institute

[@ansahsiddiqui1384]

awesome video thnx!

Isn't the 2nd ray of light supposed to look like its coming from the radius of curvature??? not from the focus and parallel to the principle axis?

[@siyabhutani2308]

ur right

[@idiosyncraticidiott5015]

thanks for the memory aid khan

[@roseb2105]

so will the image in this case be right side up?
