S 7.6.e, 7.6.f
When light strikes an object, the light can be
reflected, transmitted, or absorbed.
The color of an opaque object is the color of the
light it reflects.
When combined in equal amounts, the three
primary colors of light produce white light.
As pigments are added together, fewer colors of
light are reflected and more are absorbed.
Key Terms
• transparent • translucent • opaque
• primary colors • secondary color
• complementary colors • pigments
3 Reflection and Refraction

S 7.6.c, 7.6g
The law of reflection states that the angle of
incidence equals the angle of reflection.
When light rays enter a medium at an angle, the
change in speed causes the rays to bend, or
change direction.
An object’s position relative to the focal point
determines whether a convex lens forms a real
image or a virtual image.
A concave lens can produce only virtual images
because parallel light rays passing through the
lens never meet.
Key Terms
• reflection • law of reflection • plane mirror
• image • virtual image • concave mirror
• optical axis • focal point • real image
• convex mirror • refraction • lens
• convex lens • concave lens

image focused? (On the retina)

The camera lens camera focuses light to form a
real, upside-down image on film in the back of
the camera.
Telescopes use combinations of lenses or
mirrors to collect and focus light from distant
objects.
A microscope uses a combination of lenses to
form enlarged images of tiny objects.

When light from an object enters your eye, your
eye sends a signal to your brain and you see the
object.
Concave lenses correct nearsightedness. Convex
lenses correct farsightedness.

S 7.6.a
Mechanical waves are produced when a source
of energy causes a medium to vibrate.
The basic properties of waves are amplitude,
wavelength, frequency, and speed.
The electromagnetic spectrum is made up of
radio waves, infrared rays, visible light,
ultraviolet rays, X-rays, and gamma rays.
Key Terms
• wave • energy • medium • crest • trough
• amplitude • wavelength • frequency
• hertz • electromagnetic radiation
• electromagnetic spectrum • visible light
