Oh, right :redface: So, 1/0.0759 = 13.18cm Sorry for my dumb questions, but it's the first time I'm doing this so I'm pretty much confused :blushing:

Hmm, so if that is 1/f then f would be the inverse of that? So it would be 0.0759cm? =o

I am doing an assignment for school about the focal length of a concave mirror. I found that the focal length for the mirror was 0.0759cm-1 But, how much is that really in terms of cm? So basically, 0.0759cm-1 = ?cm Thanks ;D
