-Hello everyone. At school, I studied about convex lense and concave lense. They are very interesting, we learned about how lights would be after going through the lense. But what I want to ask is how we can calculate the distance between optical center and focal (I means focal length). Focal length is a constant, but is there any formula which can give us the value of focal length .
I would be grateful it someone could help :)
