Chapter 12: Sound - Part 1

Sound Waves

• are Longitudinal waves.

• are Surface Waves.

• are Transverse Waves

• move in a circular motion.

Sound waves that bounce off a solid surface are called

• are absorbed and lose the majority of energy.

• do not require a medium to pass through.

• reflected waves.

The process of sound waves losing energy in a porous surface is called

• reflected waves.

• do not require a medium to pass through.

• absorption.

• diffraction.

Your awareness of the energy of sound is

• absorption.

• loudness.

• reflected waves.

• diffraction.

Sound that refers to how high or low a sound seems is the

• absorption.

• loudness.

• pitch.

• diffraction.

The distance between the highest crest and the resting position of a wave marks the

• frequency.

• loudness.

• pitch.

• amplitude.

The distance a wave travels before it start to repeat is the

• frequency.

• wavelength.

• pitch.

• amplitude.

The number of times a wave repeats in a given amount of time is the

• frequency.

• wavelength.

• pitch.

• amplitude.

Sound is made when a source of energy forces the matter around it to __________.

• Vibrate

• Amplitude

• Stay still

• Pitch

Sound waves CANNOT travel through which of these:

• Paper

• Milk

• Outer space
