The model shows a special glass fiber that is thinner than some metal wires. When light enters the end of the fiber, it travels through the fiber as shown. After the light leaves the fiber, it travels –

• in a straight line

• back into the fiber

• around the fiber

• in a curve

The picture below shows a bear standing in a swimming pool. Why does the lower part of the child appear so much different in size from the upper part?

• The light rays travel through water and then into air are refracted.

• The light rays that travel through water and then into the air are enlarged.

• The light rays that travel through the air and then into the water are reflected.

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

In 1859, Henry Bursill published a book of his hand shadows. The picture below is one of these hand

shadows. Which property of light makes it possible to produce hand shadows?

• light is refracted

• light is a type of energy

• light travels in a straight line

• Light can be separated into different colors.

The diagram below shows a fish being viewed from above the water. The fish appears to be closer to the surface than it really is. What causes this difference?

• light is refracted

• light is focusesd

The diagram shows a periscope used to see objects that are behind or under a barrier. What makes it possible to see an object when looking through a periscope? The periscope -

• contains mirrors that reflect the object

• magnifies small objects so they can be seen

• absorbs the light rays passing through it

• separates the light into different colors

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
