Light Interactions

translucent

• light that bounces off an object

• construction paper

• clear window

• transmits light, but not as clearly as transparent things. More difficult to see through. It disperses much of the light.

reflect

• stained glass window

• light that bounces off an object

• glass of water

• clear window

A student placed a pencil in a cup 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

Electromagnetic energy travels in waves. When we describe electromagnetic waves, we often talk about the wave’s length and frequency. Which of these statements accurately describes the relationship between the wavelength and frequency of an electromagnetic wave?

• If wavelength increases, frequency increases.

• If frequency decreases, wavelength increases.

• If frequency remains constant, wavelength increases.

• If wavelength remains constant, frequency increases.
