Why does this car appears red under a white light?
The car is absorbing the red light and reflecting the blue and green.
The car is reflecting only the red light while absorbing the blue and green.
The car is absorbing the red and green light while reflecting the blue.
The car is absorbing the red, blue and green, but our eyes can only see the red.
In order to see an object, light must be
transmitted into your skin
reflected off the object and into your eyes
reflected off the object then off the ground then into your eyes
absorbed by your genetic material

How are we able to perceive an object as being the color white?
All colors of visible light are absorbed by an object and then reflected into our eye.
All colors of visible light are reflected off an object and then to our eye.
All colors of visible light are absorbed by an object and no light is being reflected into our eye.
How are we able to perceive an object as being the color black?
All colors of visible light are absorbed by an object and then reflected into our eye.
All colors of visible light are reflected off an object and then to our eye.
All colors of visible light are absorbed by an object and no light is being reflected into our eye.

1. Your friends say that they saw a special nail polish that changes color when it is out in the sun. Can light from the sun cause the nail polish to change color?
No. Light is not a physical thing, so it cannot change physical things like nail polish.
Yes. Light from the sun can pull energy out of the nail polish, causing it to change color.
Yes. The nail polish can take in energy from the light, causing it to change color.
No. Light can only change things by warming them up, so it cannot cause the nail polish to change color.
Jayden says that the dentist can shine a special light on his teeth that will make his teeth become whiter. Can light change Jayden’s teeth?
Yes. Jayden’s teeth can take in energy from the light, causing them to become whiter.
Yes. Light can pull energy out of Jayden’s teeth, causing them to become whiter.
No. Light can only change things by warming them up, so it cannot cause Jayden’s teeth to become whiter.
No. Light is not a physical thing, so it cannot change physical things like teeth.
Your friend says that he heard about some rocks that would glow when they were put under a certain kind of light. Can light cause rocks to glow?
No. Light is not a physical thing, so it cannot change physical things like rocks.
No. Light can only change things by warming them up, so it cannot cause the rocks to glow.
Yes. Light can pull energy out of the rocks, causing them to glow.
Yes. Rocks can take in energy from the light, causing them to glow.
When a material allows light to pass through it,
the material reflects the light and changes
the material absorbs the light and doesn't change
the material transmits the light and doesn't change
material transmits the light and changes
These graphs show the wavelength and amplitude of light coming from three lasers. Could any of these lasers be giving off a different type of light?
Yes. Laser 2 could be giving off a different type of light because Laser 2 has a different wavelength than Lasers 1 and 3.
Yes. Laser 3 could be giving off a different type of light because Laser 3 has a different amplitude than Lasers 1 and 2.
Yes. All three lasers must be giving off different types of light because every light source gives off its own type of light.
No. All three lasers must be giving off the same type of light because all three are lasers, and the same kind of light source gives off the same type of light.
Alina notices that when she shines a desk lamp on a mirror, nothing happens. When she shines an infrared lamp on the mirror, the mirror starts to get warmer. Why does light from the infrared lamp warm the mirror when light from the desk lamp does not?
Because the mirror can take in energy from infrared light but not from the light from the desk lamp.
Because infrared light carries energy, and light from the desk lamp does not.
Because infrared light carries heat molecules, and light from the desk lamp does not.
Because infrared light pulls energy out of the mirror, and light from the desk lamp does not.
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
