Question

Consider a concave mirror with a focal length
of 14.04 cm.
b) Find the image distance when the object
distance is 7.02 cm
c) Find the magnification of the image for
part b
Giving me the formulas is just fine

Answer 1

The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f):
1/f=1/d(o)+1/d(i)
The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (hi) and object height (ho).

M=h(i)/h(o)= - d(i)/d(o)
