5.5C Warm Up Jan28

An image can be seen in a shiny surface when light is –

• reflected

• refracted

• absorbed

• stopped

The picture shows what a student observed when he looked through a hand lens at a penny. What happens to light passing through a hand lens that makes the image of the penny appear larger? The light is –

• absorbed.

• reflected.

• refracted.

• stopped.

The illustration shows a light ray striking an object. In the illustration, the light striking the object is –

• absorbed.

• stopped.

• reflected.

• refracted.

Which of the following materials would reflect the most light?

• A flat sheet of aluminum foil

• A dark brown carpet square

• A smooth, black-topped table

• A piece of red construction paper

A student placed a pencil in a glass 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.

An image is produced in a mirror because light from an object that strikes a mirror –

• bounces off the mirror in straight lines.

• is absorbed by the glass in the mirror.

• adds heat energy to the mirror.

• bends as it passes through the mirror.

Students can demonstrate reflection by doing which of the following?

• Using a hand lens to enlarge an image

• Measuring a shadow made by the Sun

• Warming metal under a heat lamp

• Observing their own image in a calm lake

In the illustration above, a light bulb is shining above a bowl of water. The arrows show four possible behaviors of light rays. Which one shows the behavior of light that is being reflected?

• W

• X

• Y

• Z

This pencil in a glass of water appears to be broken, but it is not. This illusion is caused by light–

• being scattered by water molecules.

• bending when it moves from water to air.

• bouncing off the water’s surface.

• always traveling in straight lines.

Which path shows the behavior of light that is being refracted?

• W

• X

• Y

• Z
