Light Science

A teacher set up 4 mirrors, a laser and a block. The light from the laser hits the block because light

• travels in a straight line and reflects off the mirrors

• travels in a straight line and refracts off of mirrors

• travels in a curve and reflects off of mirrors

• travels in a curve and refracts off of mirrors

The image shows a glass of water in front of a sheet of paper with diagonal lines. What causes the lines in this image appear distorted?

• Light is reflected

• Light is retracted

• Light is blocked

• Light is focused

A concave lens is a curved, transparent glass that light can pass through. When light strikes a concave lens, it-

• bounces back

• makes light smaller

• refracts

• bends light

The photo shows a child with a glass jar of water holding a fish. Why does the child's face appear smaller behind the jar of water?

• Light travels in a straight line until it is refracted off the water.

• Light travels in a straight line until it passes through a new medium and is refracted.

• Light travels in a curve until it bends.

• Light travels in a straight line until it passes through a new medium and is reflected.

The diagram shows what happens when white light travels through the air into a prism. Which statement about a prism is NOT true.

• White light bends and separates into many colors.

• Light refracts.

• Light travels from one medium to another.

• Light reflects into many different colors.

A student painted one wall black and one wall white. Which color of paint will most likely appear brighter?

• White paint because more light is absorbed.

• Black paint because more light is absorbed.

• White paint because more light is reflected.

• Black paint because more light is reflected.

In this photo, a person uses his hands to make a heart shadow on the ground. The shadow has the same shape as his hands because

• light is refracted.

• light travels in a straight line.

• light passes through his hands.

• light bends as it moves through clear objects.

Some mirrors are curved to help people see objects more easily. What happens to light when it hits a curved mirror.

• Light bends as it passes through the mirror.

• Light is refracted.

• Light is reflected off of a mirror.

• Light is transmitted through the mirror.
