These waves have the highest energy of all
electromagnetic waves.
Gamma Rays
These waves have the highest energy of all electromagnetic
waves.
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?
NeitherAll EM Radiation
travels at the same speed in similar
media.
These materials absorb or reflect all
light, you cannot see through them.
Opaque Objects
These materials absorb or reflect all light, you cannot see through
them.
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 isadditive
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.
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.
