Which statement best explains why you can see yourself when you look at a mirror?
Light is refracted as it passes through the mirror.
Light is reflected, bouncing off the mirror.
Light is diffused in the mirror.
Light is reflected as it passes through the mirror.
What type of surface scatters light unevenly?

When light waves bend as they pass through a transparent medium we call this:
Refraction
Reflection
Absorption
The colors of the visible light spectrum in order from largest wavelength to smallest wavelength are:
Violet, Indigo, Blue, Green, Yellow, Orange, and Red
Green, Blue, Indigo, Violet, Red, Orange, and Yellow
Red, Orange, Yellow, Green, Blue, Indigo, and Violet
Yellow, Orange, Red, Violet, Indigo, Blue, and Green
The color that absorbs visible light waves is:
Black
White
Red
Violet
The color that reflects all visible light waves is:
White
Black
Green
Yellow
If you see the color orange, this means:
The colors red, yellow, green, blue, indigo, and violet have been absorbed and orange has been refracted.
The colors red, yellow, green, blue, indigo, and violet have been absorbed and orange has been reflected.
The color orange has been absorbed and red, yellow, green, blue, indigo, and violet are refracted.
The color orange has been absorbed and red, yellow, green, blue, indigo, and violet are reflected.
A fish bowl bending light waves and distorting an image of a cat's face is an example of:

If you were to accidentally scratch the outermost part of your eye, which part would you damage?
The cornea
The lens
The retina
The pupil
What do the lens and cornea have in common?
They both send messages to the brain.
They can both change shape.
They both contain photoreceptive cells.
They both bend light into a focused beam.
What would happen to your pupils if it's extremely bright outside?
They would let a lot of light into your eyes
They would expand and become very large
They would contract and become very small
They would close up completely
Which part of your eye is most like the film in a camera?

The pupil
The lens
What role does your brain play in the process of seeing?
It puts blurry images into focus.
It turns black-and-white images into color.
It flips upside-down images rightside-up.
It flips backwards images over so you see them the correct way.
What might happen if the lens of your eye became damaged?
Your eyes wouldn't be able to focus properly.
You wouldn't be able to see in color.
You wouldn't be able to see at night.
All the images you saw would be upside-down.
Why do some people have blurry vision?
because the back of their eye is too far or close, and the image they see is not focused
because their eye is broken so they can't see
because they put too many eye drops in their eyes and now they have milk in the back of their eyeball
What is the retina?

What is the pupil of the eye?
the back part of the eye where the image is formed
the front part of the eye that is clear
the black part that light goes through
the colored part
What is the iris of the eye?
the back part of the eye where the image is formed
the front part of the eye that is clear
the black part that light goes through
the colored part of the eye
