(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

More mirrors. Object O stands on the central axis of a spherical or plane mirror. For this situation (Table 34-4 below. All distances are in centimeters.) , find (a) the type of mirror (0 depicts "plane", 1 - "concave", 2 - "convex"), (b) the radius of curvature r (nonzero number or 0 if infinity), (c) the object distance p, (d) the image distance i.

f= -42

m= +0.26

(a) 2

(b) -84

(c)

(d)

3. The attempt at a solution

So I'm stuck mainly because the focal length (f) is negative. I think since f is less than m the mirror is convex. Would I still solve for p the same way?

p= (1 - (1/m))*f

so

p= 199.538 cm

and then equals

i = -mp

i = -51.8799

Am I right?
