What might happen to an object sitting on top of a speaker if loud music is played through the speaker?

• Absolutely nothing would happen to the object.

• The object could move due to the vibrations of the sound.

• The object could appear a different color because the sound is absorbed.

• The object could stop the sound from being transmitted out of the speaker because sound cannot travel through a solid.

What is a pitch (as it relates to sound)?

• the intensity of a vibration

• the amplitude of a sound wave

• volume of sound

• highness or lowness of a sound

Which of these waves would have a higher pitch?

• Low Frequency

• High Frequency

• Frequency does not determine pitch

What happens when you increase the amplitude of a sound?

• It makes the sound travel faster

• It makes the sound louder

• It increases the wavelength of the sound

• It increases the frequency of the sound
