Concave Mirrors
"Take first an
object in the region between the mirror and focal point. The nearer
the object is to the focal point, the weaker the intensity of light
will be, but the larger the image will be. The farther away the
object is from the focal point (closer to the mirror), the stronger
the intensity of light will be, but the smaller the image will be.
In both cases the image will be upright."
a. verify these statements...

Background information
A person with normal vision can focus on objects as close as a few
centimeters from the eye up to objects infinitely far away. There
exist, however, certain conditions under which the range of vision
is not so extended. For example, a nearsighted person cannot focus
on objects farther than a certain point (the far point), while a
farsighted person cannot focus on objects closer than a certain
point (the near point). Note that even though the presence...

A concave lens refracts parallel rays in such a way that they are
bent away from the axis of the lens. For this reason, a concave
lens is referred to as a diverging lens.
Part A
Consider the following diagrams, where F represents the focal point
of a concave lens. In these diagrams, the image formed by the lens
is obtained using the ray tracing technique. Which diagrams are
accurate?(Figure 1) (Figure 2) (Figure 3) (Figure 4)
Type A if...
