How are light and sound waves different?

• They all have similar wavelengths

• Only light transfers energy

• Light waves can travel through a vacuum, while sound waves cannot

• Sound waves oscillate.

How do the frequencies and the speeds of red light and violet light compare?

• The frequency of red light is greater than that of violet light, while the speeds of both colors of light are the same.

• The frequency of violet light is greater than that of red light, while the speeds of both colors of light are the same.

• The frequency of red light is the same as that of violet light, while the speed of red light is greater than that of violet light.

• The frequency of violet light is the same as that of red light, while the speed of violet light is greater than that of red light.

When piano strings vibrate, waves move in both directions along the string, interfering with each other. Sometimes these wave interact to make nodes and antinodes. What are these kinds of waves called?

• electromagnetic waves

• superposition waves

• standing waves

• seismic waves

As waves move through water, the water at any point rises and falls. At a given moment, two points along the wave’s line of travel that are 2 meters apart have each risen to form adjacent troughs. Which measure is described by this observation?

• wavelength

• frequency

• The speed of the wave

• The amplitude

Suppose that the convex mirror is placed so that a candle is between the focus point F and the mirror. What happens to the image of the candle?

• The image appears taller and on the same side of the mirror.

• The image appears behind the curved mirror and taller.

• The image appears shorter and on the same side of the mirror

Why does white light bend and turn in to colored light in a prism?

• Although the light changes speed, it continues in the same direction as before.

• Although the light bends, its speed remains the same as before.

• Light bends due to the difference in the speed of light in air and glass
