How do you know where the focal point is when you begin drawing a ray diagram?

[fizzicsorg]

@PCgam3r14 You have to have at least a two of bits of information before the diagram can be drawn, choice from focal length, the image position or the object position. The focal length can be found experimentally, as shown in the video.

i have a question:: why does my teacher make things so much harder than it really is!?? lol i get it sooo much more now, thanks!!

What do you mean 'incomplete' - it is just a link to this video... the site is not every physics topic at every level... only what I need students to look at outside the lesson...

Thank you - that will be helpful to my students.

Is it possible to have a hollow dome shaped lense, with an inner diameter of 5m lets say, to catch light from various angles and refract it all perpendicular to the flat of the dome (ie the ground)? if so, what curvature and how thick would the glass be? Thanks a lot.
