The object appears white then changes to appear green.
The object appears blue then changes to appear black.
An apple appears red, while an egg appears white to the human eye. Which diagram correctly demonstrates why each object appears the color seen by the human eye?
One at a time, Sam observes different colored objects using three different colored filters. His observations are shown in the chart. What can be inferred from the data?
Color filters absorb all colors that passed through them.
Color filters reflect all colors that passed through them.
The color of an object is the light that is reflected by the object.
The color of an object is the light that is absorbed by the object.
Use the figure showing the structure of the eye with parts labeled X, Y, and Z to answer the following question. Which statement describes the structure of the eye labeled Z?
It is the retina, which reflects all the light rays falling on it.
Is the optic nerve which refracts all the light rays falling in on it.
It is the optic nerve, which transmits the nerve impulses to the brain.
It is the retina, which consists of nerves that transfer the energy of light waves.
The human eye is a complex structure with many parts that function together to enable sight. Through what parts of the eye is light refracted?
K and L
P and O
L and P
J and M

Sample one is blue, and Sample two is black.
Sample one is blue and simple two is white.
Sample one is black and simple two is blue.
Examine the diagram of the eye. Why is structure 7 so important?
The optic nerve relays electrical signals to the brain where they are interpreted.
The cornea adjusts the amount of light entering the eye by closing and opening.
Cones allow the eye to respond to bright stimuli and to have color vision.
The lens bends light passing through the eye and changes shape to focus the light.
