Amplify Science Waves

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.

If objects are lined up as shown in the diagram, the red laser light will touch all of the objects. What does this evidence prove? (select all that apply)

• Light travels in a straight line.

• Light is absorbed by some objects, but not others.

• Light is transmitted by some objects, but not others.

• LIght is reflected by some objects, but not others.

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

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

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.

Maya wonders which types of light could heat up a sheet of aluminum. The table below shows what happens when different types of light hit the aluminum.

• The X-ray light is more likely to heat up the aluminum because the X-ray light can pull energy out of the aluminum when it passes through the aluminum.

• The ultraviolet light is more likely to heat up the aluminum because the ultraviolet light bounces off the aluminum, which means that it has more energy.

• There is no way to know because they are two different types of light, and different types of light can change a material in different ways.

• Neither type of light is likely to heat up the aluminum because the aluminum does not take in energy from either the X-ray light or the ultraviolet light.
