# Simple lens law

In this video we'll explore the algebra of light rays which are in focus.

• I don't understand the simple lens law
• Howdy,

So this is useful, and we have been looking intuitively about how you move an object closer to the lens, then the projection will be closer, and the opposite is true for an object farther away, is that correct?

Well, is there a mathematical equation that can help us solve for the distance that i_ will be; aka the i that is the distance from the pinhole to where the image will be projected. How can we find the _exact distance to it, thanks! :-)
• I have NO idea what this means
• Why would you use simple lens laws?
• why is this an advanced math lesson?
• To easy for me about mathematics 10 !)11”13
• ay why you do this to me my iq is 00000000.12
