What is different about the speed of sound waves vs. the speed of light?

• sound waves are the FASTEST in solids (high density), while light waves are the FASTEST in gas (or no molecules)

• sound waves are the FASTEST in gas (low density), while light waves are the FASTEST in solids

• Both have the same speed all the time

• Both are the FASTEST in the air or gas (low density)

Why would a wave change direction?

• Because it went from one medium to another.

• Because the amplitude was too large.

• Because the frequency was too small.

• Because the wavelength remained the same.

If a satellite or spaceship explodes in outer space, you can see the explosion from a distance but you cannot hear it. Why?

• Light waves travel very slow and sound waves travel much faster.

• Sound waves transmit energy while light does not transmit energy.

• Sound is a mechanical wave and needs a medium to travel through while light is an electromagnetic wave.

• Light is a mechanical wave and needs a medium to travel through while sound is an electromagnetic wave.

Why do people tend to cup their hands around listeners' ears when whispering to them?

• The ear cannot absorb sound waves produced by a whisper without a cupped hand.

• Solid objects, such as a cupped hand, can direct sound waves into the ear of the listener.

• Sound waves from a whisper are short; they will not reach the ear unless guided by a hand.

• A cupped hand makes the sound echo so the listener can hear more clearly.

Sound can travel through

• soild

• liquid

• gases

• all of the above
