• air

• steel

• water

• a vacuum

Which of these waves can NOT travel through the vacuum of space?

• microwaves

• radio waves

• light waves

• sound waves

Sound waves are transferred by the compression of particles. The closer the particles are to one another, the faster the energy is transferred. Therefore, sound energy directly depends upon the _________ of the medium.

• density

• mass

• pressure

• volume

Houses with carpet are much quieter than houses with tile or hardwood floors because of sound wave

• absorbtion

• diffraction

• reflection

• refraction

You attend a football game one day and notice a long time difference between when the other side of the stadium stands up to cheer and when you hear them. This time difference would be lessened if

• it were warmer

• it were less humid

• it were located a high altitude

• the fans on the opposite side were louder

If we compare and contrast electromagnetic waves with sound waves, all BUT one statement is true. That is

• sound waves require a medium to travel while electromagnetic waves do not.

• electromagnetic waves can travel through the vacuum of space while sound waves cannot.

• electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere.

• sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.
