By passing light through a prism, you can tell _______________
that blue light is brighter than white lights
that white light is made up of different colors
the original source of light
the weight of the prism
White light is made up of every color of the rainbow. As white light passes through a prism, it is refracted and these colors are produced. They are always in a certain order. Which two colors are missing in the diagram?
yellow and blue
yellow and white
blue and purple
pink and blue
What color appears when all colors are absorbed?
red
violet
white
black
Materials such as wood and metal do not let light travel through them. We cannot see through them at all. They are said to be _____________.
invisible
translucent
transparent
opaque
Light can pass through some solids, liquids, or gases. Materials that allow light to pass through them clearly are called transparent. Which of the following materials is NOT transparent?
water
a mirror
clean air
window glass
Which of these is an example of a translucent object?
waxed paper
book
opaque
glass
What happens to light when it strikes an opaque surface?
The light is refracted back and separated into colors.
The light passes through with no charge.
The light does not pass through the opaque surface.
The light curves around the opaque surface entirely.
When light hits a translucent object, the light is _________
reflected
scattered
refracted
laminated
Which example shows light being reflected?
Using a microscope to make small objects look larger.
Using eyeglasses to see things better.
Using a mirror to see your image.
Using a prism to show the colors of that spectrum.
The picture shows a pencil in a container of water. Why does the pencil look as if it's broken?
Because light rays are bent when they pass from air into water and from water into air.
Because the water separates the light into many colors.
Because the shiny glass reflects light.
Because the part of the pencil outside the water casts a shadow by the water.
How does light react in an opaque blue material?
It is refracted.
All the light is absorbed.
All the light is absorbed except the blue which is refracted.
All the light is absorbed except the blue which is reflected.
When light bounces off a smooth surface, this is known as which of the following?
deflection
reflection
refraction
absorption
This picture shows a duck swimming in a lake. A student sees a mirror image of a duck in the water off the lake. What causes this mirror image?
reflected light
refracted light
absorbed light
black light
Which of the following allows you to see object that do not produce their own light?
absorption
refraction
reflection
deflection
Bending of light as it passes from one material to another is known as which of the following?
absorption
mirror image
reflection
refraction
Brightness of light is related to the amount of light being seen. The closer in distance to the source of light, the ____________ the light appears.
dimmer
waiver
brighter
darker
How does your eye see color?
Light hits an object & the color is reflected. Your brain interprets color.
The light hits an object & is reflected. Your eye determines the color.
Light hits an object & is refracted & somehow finds its way into your eye.
The color is just there. Your eye decides what color objects are.
