Light waves travel the
fastest through which
medium?
A vacuum
What determines the color of
light?
It’s wavelength
What is an object that
reflects some light and
transmits some light
called?
translucent
What type of
material reflects the
most amount of
light?
opaque
What type of material lets
nearly all light through?
Transparent
Which way does a concave
mirror curve? Convex?
Concave: Inward
Convex: Outward
What kind of reflection type
(converge/diverge) does a
concave and convex mirror
have?
Concave: Converge
Convex: Diverge
Where is a concave and
convex lens thickest?
Concave: Thicker Edges
Convex: Thicker middle
Is the image smaller or larger for:
1) A concave mirror with the
object between the focal
point and mirror?
2) A concave mirror with the
object beyond the focal
point?
1) Between focal point:
Larger
2) Beyond Focal point:
Smaller
Is the image upright or inverted for:
1) A concave mirror with the
object between the focal
point and mirror?
2) A concave mirror with the
object beyond the focal
point?
1) Between focal point:
Upright
2) Beyond Focal point:
Inverted
What is the difference
between a mirror and a lens?
Mirror: Reflects light
Lens: Refracts light
What is the difference
between reflection and
refraction?
Reflection: light wave bounces
off a surface
Refraction: light wave bends
as it passes from one medium
to another due to the change
in wave speed
What is the difference
between regular and diffuse
reflection?
Regular Reflection: occurs with
smooth surfaces and results in a clear
image because the light rays reflect
normally
Diffuse Reflection: occurs with rough
surfaces and results in no clear image
because light rays reflect in different
direction
What type of
reflection occurs when
light rays are caused
to scatter?
Diffuse Reflection
What is the law of
reflection?
Law of Reflection: the
angle of incidence is equal
to the angle of reflection
What is the straight line
drawn perpendicular to the
center of a mirror called?
Optical Axis
What is thin, flexible, and
transparent that can make
light travel in curved paths
using total internal reflection
called?
Optical Fibers
When you look through
a tinted, transparent
filter, what color will
you see?
The color that is
transmitted
What is true about an object
that appears red?
1. It reflects red light
2. It absorbs all colors
except red
3. It may be made of yellow
and magenta pigment
What is used to see detailed
images of distant object
using a concave mirror,
plane mirror, and eyepiece?
Reflecting Telescope
What are the 3
primary colors?
Red, Green, Blue
What are the 3 primary
pigment colors?
Magenta, Yellow,
Cyan
If an object absorbs all
the light that hits it,
what color does it
appear?
Black
What color do the primary
light colors make when they
overlap?
White
The color that an object
appears is the color of
light it _________. The
object _________ all of
the other colors.
The color that an
object appears is the
color of light it reflects.
The object absorbs all
of the other colors.
