A student placed a pencil in a cup of water. The pencil appears broken because light

• always travels in a straight line.

• bends when it passes through water.

• makes the water in the glass evaporate.

• reflects the pencil on the water's surface.

Which color of light is most refracted during dispersion by a prism?

• red
• yellow
• green
• violet

Why is the spectrum of light separated into its components of color when white light is directed to a prism?

• Because light reflects off the prism's surface

• The incident white light refracts and separates into its constituent colors

• 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
