What kind of frame of reference do I have to choose when I'm studiyng lens and mirrors?
As far as I know you consider positive the direction where the rays are real and negative the one where the rays are virtual, is that always true?
Why can't we study a problem of optics choosing a frame of reference as we are supposed to do when we are studiyng a problem of dynamics?
Is there a more formal motivation?
As far as I know is because the equation 1/p + 1/q = 1/f is correct only when we are considering negative the virtual rays and positive the real ones, the same for mirrors.
Just another thing, why is that equation correct also for mirrors? I know the demonstration but is there something Inew the nature that makes this special
