Multiple Choice

What image show light being reflected?

Multiple Choice

What image show light being absorbed?

Multiple Choice

What image show light being transmitted?

Multiple Choice

What do we need in order to see?

• A light source and objects that reflect light

• Only the sun

• Darkness

• A mirror

Multiple Choice

What happens to light waves when they strike an object?

• They are all absorbed

• They are all reflected

• Some are absorbed, some are reflected, and some pass through

• They disappear

Multiple Choice

What determines the color of an object?

• The light source

• The wavelengths of light it reflects

• The temperature of the object

• The size of the object

Multiple Choice

What causes the apple to appear red to humans?

• It reflects all wavelengths of light

• It absorbs all wavelengths of light

• It reflects only red wavelengths of light

• It emits its own light

Multiple Choice

A shirt appears yellow under normal white light conditions. What color does it appear if illuminated with bright greenish-blue light?

• Black

• Green

• Yellow

• Red

• Purple

Multiple Choice

Why is the spectrum of light separated into different colors when white light passes through a prism?

• Because light reflects off the prism's surface

• Refraction causes the light to bend

• The white light is absorbed by the prism, separating its colors

• The light speeds up as it moves from air into the denser plastic material

Multiple Choice

Which explains why the fork looks different under water?

• light can't pass through the glass
• the wavelength of light lengthens
• the amount of light increases when going through water
• light is refracted at an angle

Multiple Choice

Which picture shows diffraction?

Multiple Choice

Do light waves diffract easily?

• Yes.

• No.

• Maybe.

• Depends.

Multiple Choice

Olivia is in a science class experimenting with different materials to see how well light passes through them. Which is true about the materials presented?

• Glass and apple are examples of opaque objects it blocks all the light.

• The paper in the middle is considered a translucent object.

• Paper and apple are examples of transparent objects.

• All the objects presented are examples of opaque materials.

Multiple Choice

A leaf is green because

• All colors are reflected except green

• The light is not part of the EM

• All colors are absorbed except green

• The sun light shining on the leaf is green
