What do opaque materials do to light?
They do not
transmit
light
View source
What do opaque materials produce?
Shadows
View source
Why can you predict the size and shape of shadows?
Because light travels in
straight lines
View source
What is the law of reflection?
The
angle of incidence
equals the
angle of reflection
View source
What is an incident ray?
The ray that strikes the
mirror
View source
What is the normal line in reflection?
An imaginary line at
90°
to the mirror
View source
How do you measure angles in reflection?
From the
normal
to the
rays of light
View source
What happens when light is reflected from a mirror?
The
angle of incidence
equals the
angle of reflection

reflects
red light and
absorbs
others

refracted
more
