to create a spot light, but only have convex lenses and concave mirrors (at varios focal lengths) as materials to do so.

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.

ahh i see thank you for your help, i appreciate it :)

ok thank you for your help :)

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...

Hi all, if light was to go straight through a convex lens would it come out straight or inverted to a point? also if light was to go through the same lens but goes through going inwards how would the light be refracted?

try hitting different types of balls. try for example a shutle coff it still makes the popping sound but at a different frequency. it has to do with the weight of the object that has been foced into the strings on the racket. it is basically a sum up of the other people replying to this but i...

lenses and mirrors?? hi all, i was wondering what would happen if a convex lens and a concave mirror were set up one after another, the convex len being first to receive the light. how would this work in spot lights? i don't see howa spot light can have a tightly focused spot on a stage, i...

I am really stuck on what to do. "The completed lantern needs to produce a tightly focussed spot of light on a stage, it is positioned 12m horizontally away from it and 5m above it. It also has to fit a box that is 30cm long" Parts avaliable: light bulbs light bulb holders wiring...
