if the set up goes a light, a convex lens, then a concave mirror how would the light rays reflec off the concave mirror.. that's what i am trying to figgure out.
Thank you aresnick it did help me out a bit.
what if you had to use only concave and convex lenses and mirrors to create the tightly focused spot? when i drew a set up of a light, then a convex lens, then a concave mirror the mirror relfects the light back towards the lens, so would that mean i...
apologies on the description. what it was meant to say is that if rays of light are straight before they go through a convex lens would it come out straight or will the light be refracted and bent to make a point? the other one is if the light was already bent to create a point would it come out...
