In this GIF, which of the vocabulary represents what is happening in the GIF?
Absorption
Reflection
Transmission
What does the term reflection mean?
When an object takes in the light
When light passes through an object
When Light bounces off an object
Which type of light wave can cause sunburns or even skin cancer?
x-ray
visible
ultraviolet
The energy in ________ light from the sun, gets ________ by the genetic material in the skin cell. This causes the genetic material to be _________.
infrared, reflected, damaged
ultraviolet, absorbed, damaged
ultraviolet, reflected, increased in kinetic energy
A student placed a pencil in a cup of water. The pencil appears broken because light
always travels in a straight line.
slows down when it passes through water.
makes the water in the glass evaporate.
reflects the pencil on the water's surface.
When light goes from a less dense to a more dense medium,
it is bent towards the normal.
it always lies along the normal.
it is unaffected.
it is bent away from the normal.
Why is the spectrum of light separated into its components of color when white light is directed to a prism?
Because light reflects off the prism's surface
The incident white light refracts and separates into its constituent colors
The white light is absorbed by the prism, separating its colors
The light speeds up as it moves from air into the denser plastic material
What is incident ray?
the ray which forms 90 degree with surface
the ray which passes through the surface
the ray which strikes any surface
the ray which is deflected by a smooth surface
What is the reflected ray?
The ray which forms 90 degree angle with the surface
The ray which gets deflected from the surface
The ray which passes through the surface
The ray which strikes the surface
The angle of incidence equal to the angle of reflection.
True
False
Shadows occur longest in ________
Noon
Morning
Afternoon
Evening
Light is a ______ object
Liquid
Gas
Solid
None of These
Light passes through Opaque objects
True
False
What can we see when we look into a mirror
Refraction
Inverted Image
Reflection
Mirror
What type of wave is a light wave?
A sound wave
A seismic wave
A electromagnetic wave
A mechanical wave
Which letter is an example of reflection?
A
B
C
Which statement best describes visible light?
The human eye can only detect visible light as white light.
Visible light can only be seen with special equipment or technology.
Visible light makes up a small part of the electromagnetic spectrum.
The frequency of visible light is the same as the frequency of gamma rays.
Which is the correct sequence of events that allows human eyes to see
green grass?
Light is produced. All light waves reflect off the grass. The human eye sees the image as green grass.
Light is produced. Green light waves reflect off the grass.The human eye sees the image as green grass.
Light is produced. All light waves are absorbed into the grass. The human eye sees the image as green grass.
Light is produced. Green light waves are absorbed into the grass. The human eye sees the image as green grass.
A student looks at a mirror and then at a piece of shiny aluminum foil.
Why is the image in the mirror clearer than the one in the aluminum foil?
The mirror absorbs more light than the aluminum foil.
The aluminum foil produces more light than the mirror.
The mirror reflects more light without scattering the light.
The aluminum foil reflects more light without scattering the light.
What has most likely occurred if light travels into an object without bouncing off?
absorption
reflection
refraction
scattering
A person places a red apple under blue light. How will the person report the color of the apple?
as red
as blue
as black
as white
Which best explains how the human eye perceives color?
Visible light is absorbed into an object; the light is projected through the human pupil to the cones, which decipher color.
Visible light is reflected off of an object; the light is projected
through the human pupil to the cones, which decipher color.
Visible light is absorbed into an object; the human iris deciphers the color.
Visible light is reflected off an object; the human iris deciphers the color.
In order for materials to change, they need to ________ energy from light
emit, or give off
absorb, or take in
What effect of light does this picture show?
Transmit through
Reflect off
