OF LIGHT
QUALITATIVE
CHARACTERISTIC
OF IMAGES

2.
Predict the qualitative characteristics (orientation,
type, and magnification) of images formed by plane
and curved mirrors and lenses.
Identify ways in which the properties of mirrors
and lenses determine their use in optical
instruments (e.g., cameras and binoculars)

light into the same
medium after striking
a surface

1
The angle of
incidence is
equal to the
angle of
reflection.
2
The incident ray,
the normal line
and the
reflected ray lie
in one plane.

15.
● upright/erect
● the same size as the object
● the same distance behind the mirror
as the object in front of the mirror
● laterally reversed
● virtual

16.
● No light actually passes at the
apparent location of the image.
● Formed at the back of the mirror.
● It cannot be focused on a screen.
● It is always upright.

17.
The
smaller the angle
between the mirrors, the
greater the number of images
formed on the mirror.
