The optical power ofan optical device of focal length f is ? = 1/f,the unit of which is 1/m or m–1 ordiopter. An image is described as real or virtual, inverted ornoninverted, reversed or unreversed, magnified or minfied, and onthe same or the opposite side as the object.
A concave mirror hasa focal length of f = +1.250 m.
(a) Find the opticalpower of the mirror, ?.
An object is placeda distance p = 10.0 m in front of the mirror.
(b) Find the imageposition, q.
(c) Find themagnification, M.
(d) Describe theimage.
The object is nowmoved so that the object distance and the image distance are the same, p = q.
(e) Find the objectdistance, p, or image distance, q.
(f) Find the magnification, M.
(g) Describe the image.
The object is nowmoved so that the image distance is q = 5.0 m.
(h) Find the object distance, p.
(i) Find the magnification, M.
(j) Describe the image.
The object is nowmoved so that the magnification is M = +5.0.
(k) Find the object distance, p.
(l) Find the image distance, q.
(m) Describe the image.
