REFLECTION
OF LIGHT
QUALITATIVE
CHARACTERISTIC
OF IMAGES

5. 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)

8. bouncing back of
light into the same
medium after striking
a surface

12. 𝜽𝒓
angle between the
reflected ray and the
normal line

13. line perpendicular to
the surface

14. the ray that rebounds
from the surface

15. the ray that strikes the
surface

16. 𝜽𝒊
angle between the
incident ray and the
normal line

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.

24. ● 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

25. ● 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.

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

28. 𝑵 =

• N is the number of images
• θ is the given angle

30. position the mirrors parallel with
each other or facing each other

32. diagram that traces the
path that light takes
in order for a person to view
a point on the image of an
object

33. incident ray
reflected ray
