Put these in order of
increasing energy:
FM Radio Waves,
Gamma rays,
Infrared Light,

Gamma rays,
These waves have the
highest energy of all
electromagnetic waves.
These waves have the
highest energy of all electromagnetic
waves.
Gamma Rays
This is the only
part of the
electromagnetic
spectrum you can
see.
This is the only
part of the electromagnetic spectrum you can see
Optical Range
(visible light)
.
Which travels faster,
red light or blue
light?
Which travels faster,
red light or blue light?
Neither
All EM Radiation
travels at the same
speed in similar
media.
These materials
absorb or reflect all
light, you cannot
see through them.
These materials absorb or reflect
all light, you cannot see through
them.
Opaque Objects
A green filter absorbs
these colors of light
A green filter absorbs these colors of light
Red and Blue light
are absorbed. Only
Green is transmitted
What color is formed
when all three primary
pigments are mixed?
What color is formed when all three primary
pigments are mixed?
BLACK
Red light and Green
light combine to form
yellow light so the light
is
(additive/subtractive)
color.
Red light and Green light
combine to form yellow
light so the light is
additive
color.
This color of light has
the shortest wave
length and the highest
energy.
This color of light has the shortest
wave length and the highest energy.
VIOLET
This is the word
used to describe
light that strikes an
object.
This is the word used to describe light
that strikes an object.
Incident Light
This is the result of
waves changing
velocity when they
travel from one
medium to another.
This is the result of waves changing velocity
when they travel from one medium to
another.
Refraction
This is what happens
when waves are bent
around a barrier.
This is what happens when waves are
bent around a barrier.
Diffraction
What type of interference
is taking place as the
crests combine to form
new colors of light?
What type of interference is taking place as the crests combine
to form new colors of light?
Constructive Interference
Calculate the angle of
reflection in the diagram.
Angle of reflection is 30°
Law of Reflection =’
This is the type of
image produced by a
plane mirror.
(3 Characteristics)
This is the type of image produced by a
plane mirror.
(3 Characteristics)
A Virtual, Upright,
True Size Image
This is the name for the
structure n the picture.
Concave Mirror
This type of image
is produced when
the light rays
actually cross and
touch the image.
This type of image is produced when the
light rays actually cross and touch the
image.
Real Image
A convex mirror and a
concave lens both produce
this kind of image due to
wave divergence.
They both produce a
Virtual, Upright, Smaller
Image
This is where the object
must be placed to produce
a real, inverted image with a
convex lens..
This is where the object must be placed to
produce a real, inverted image.

Laser light is made
up of this type of
light to produce a
concentrated beam.

Light travels
fastest in this
medium.
Light travels fastest in this

A vacuum
This type of filter only
lets light of one
orientation pass
through.
This type of filter only lets light
of one orientation pass through.
Polarizing Filter
This technology uses
the principal of Total
Internal Reflection to
transmit messages
with light.
