Why can't you hear in space?

• In space it is too cold for sound to travel.

• You can't hear in space because there are no rocks for the sound to bounce off of.

• There is no medium in space for sound to travel through.

• If you were in space, you really could hear.

How does increasing the length of a vibrating object affect the FREQUENCY of a sound that is produced?

• The frequency would remain the same.

• The frequency would also increase.

• The frequency would decrease.

• There frequency would be ZERO.

How is the speed of sound affected by an increase in air temperature?

• As the temperature increases, the speed decreases.

• As the temperature decreases, the speed decreases.

• Temperature has no affect on the speed of sound in air.

What is the relationship between frequency and pitch in sound waves?

• Frequency affects only the loudness, not the pitch.

• Higher frequency results in higher pitch.

• Higher frequency results in lower pitch.

• Frequency and pitch are unrelated.

• Amplitude

• All of the above

• Wavelength

• Frequency
