Physics: How much is cm-1?
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

cm^(-1) written with the -1 as a power indicates that the units are 1 / cm.
Are you sure it's not 1 / f = 0.0759 cm^(-1)?
That would make sense, and taking the reciprocal:
f = 1 / 0.0759 = 13.2 cm.
