Hey thank you so much this was really useful! Just wanted to know what you recommended doing when you aren't given a focal point/principle focus and asked to either draw the diagram without, or put the focal point in yourself? (The question I was given didn't have any rays drawn either)
@s.m.3867 ай бұрын
In that case make sure the two focal points are equally distanced, as long as you do that, the distance in amount doesn't matter, and everything else you can just do as shown in the video. Hope this helps~

Hi, we say that concave lenses are diverging lenses because they cause the light rays to bend away (diverge) from the axis. Convex lenses are converging lenses :)
