Which of the following best models how light is reflected?

• An arrow hitting a target

• A ball bouncing off a wall

• An apple falling from a tree

• A marble rolling down a ramp

Students often use a hand lens to make small objects appear larger. A hand lens makes objects appear larger because the lens-

• increases the light’s strength

• changes the color of the light

• bends light passing through it

• converts light energy to heat

Light traveling through the air moves in a straight line. An object viewed through water looks different because light rays that travel through water are –

• bent.

• bounced.

• reflected.

• absorbed.

___________ travels in a straight line until something changes its path

• Medium

• Refract

• Reflect

• Light

Why does the straw appear to be bent?

• light is reflected

• light is absorbed

• light is turned

• light is refracted

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

• absorbed
• stopped
• reflected
• refracted

Why does the lower part of the child appear so much different in size from the upper part?

• The light rays that travel through water and then into air are refracted.
• The light rays that travel through water and then into air are enlarged.
• The light rays that travel through air and then into water are reflected.
• The light rays that travel through air and then into water are reduced.

What might explain why light travels in a straight line?

• If there is nothing to interfere with light waves, they should travel in a straight line.

• Light waves will always travel in a straight line, even if they come into contact with another object.

• Light waves don't travel in a straight line.

• Light waves travel in a straight line because sound waves travel in a straight line.
