Properties of Light
Prism
A piece of glass that separates white light into colors of the spectrum.
Obaque
Allowing no light to pass thru (solid)
Translucent
Allowing some light to pass through (frosted glass)
Refraction
Bending of light
prism

It travels in waves
How does light travel?
It must either give off its own light or it must reflect light
In order for something to be visible, what must happen?
White Light
Ordinary light, such as daylight, and is made up of all colors of light mixed together
Intensity
The brightness or dullness of a color
Sun, phone, watch, lightning, lamp, flashlight, fire
What are sources of light/energy?
The different amount of energy in white light.
What are the different colors related to?
only visible light
What best describes the range of colors the human eye can see?
the colors of the rainbow
What describes a visible spectrum?
Red, orange, yellow, green, blue, indigo, violet
What does ROY G BIV stand for?
The intensity of light. The amount of light the eye receives from the source.
What does brightness mean?
The bulb will look less bright
What happens if you move farther away from a glowing light bulb?
The greater the intensity or degree of brightness
What happens the closer the light source is?
The less the intensity or brightness.
What happens the greater the distance from the light source?
it changes back into white light
What happens when a spectrum of colors passes through a prism?
all of it passes through
What happens when light hits clear glass?
The white light is separated into light of different colors
What happens when light passes thru a prism?
people can see it
What happens when light reflects off an object?
The different colors of light that are revealed when white light passes thru a prism.
What is a light spectrum?
type of energy
What is light?
Frosted glass

Plants to grow
What is the sun's light needed for?
Glasses, shoe, mirror, book, water, pencil
What reflects light?
Light is a form of energy
What statement about light is true?
Light and heat energy from the sun
What warms the earth?
Earth would be freezing cold
What would happen without the light and energy from the sun?
It would be dark and you would not be able to see anything.
What would the world be like if there was no light?
refraction
When light rays travel through air and enter water they slow down and bend. What is this change in direction called?

Visible
able to be seen
Transparent
allowing light to pass thru (clear)
Brightness
intensity of light
Color
light reflected off an object
Energy
the ability to do work
Reflection
the bouncing back of a ray of light when the ray hits a surface that it does not go through
Absorption
when light is not reflected or refracted in an object
