a
b
c
d
9
Multiple Choice
In the illustration, the light ray striking the object is-
10
Laws of Reflection
the angle of reflection is = to the angle of incidence
the incidence ray and reflected ray are on opposite sides of the normal line
the incidence ray, reflected ray, and normal line all lie on the same plane
11
Multiple Choice
12
Multiple Choice
In the diagram, which letter represents the angle of incidence?
A
B
C
D
13
Keep in mind
to view the image it must be in the line of sight
The law of reflection is true regardless of the mirrors orientation
14
Multiple Choice

19
Formation of an Image
light emanates from various directions
some of the light rays reflect off a mirror surface due to the laws of reflection
a flat plane mirror will produce a virtual image where the light rays extend backwards interseting at a point behind the mirror
20
Multiple Choice
Why do mirrors appear to flip images or letters
apparent image reversal
the image is reversed
the image is magnified
the image is flipped
21
Apparent Image Reversal
the image appears to flip right and left sides
22
Multiple Choice

real
larger
same size
smaller
