Properties of Visible Light

A student places a pencil in a glass of water and observes that the pencil appears to be broken. Which of these provides the best explanation for why the pencil appears broken?

• The pencil absorbs all the lights rays that hit it.

• Water reflects light rays away from the pencil.

• Light rays are bent by the water in the glass.

• The surface of the water reflects light rays.

The distance from Earth to the Moon can be accurately calculated by pointing high-powered lasers onto the Moon’s surface. The time it takes for the light to return is used to find the distance. To make this possible, astronauts on the Apollo 11 Moon mission had to place a device on the Moon that would –

• store the laser light for future use.

• bounce the laser light back to Earth.

• allow the laser light to pass through.

• change the frequency of the laser light.

Solar panels generate electricity using photovoltaic cells that receive sunlight. To protect these cells from moisture while allowing sunlight to pass through, engineers must design a cover for the solar panel that is –

• waterproof and transmits light.

• very flexible and reflects light.

• stronger than steel and bends light.

• cold to the touch and absorbs light.
