Unit 8 Mechanical Waves Test 5 of 20 Which correctly describe the properties of sound waves? Sound is a mechanical wave that travels ; faster in denser mediums, and cannot travel through space, because there would be no medium i to carry the energy. Sound is a mechanical wave that travels slower in denser mediums, and can travel through space, because there would be no medium to slow the energy. Sound is an electromagnetic wave that travels faster in denser mediums, and cannot travel through space . because there would be no medium to carry the energy. Sound is a mechanical wave that travels faster in denser mediums, and can travel through space, because there would be no medium to slow the energy.

## Step 1<br />Sound is a type of mechanical wave. Mechanical waves require a medium to travel through, such as air, water, or a solid substance. This is because they are created by the vibration of an object, which then causes the surrounding medium to vibrate and transfer the energy from one particle to another.<br /><br />## Step 2<br />Sound cannot travel through space because there is no medium in space to carry the energy. Space is a vacuum, meaning it has no particles to vibrate and transfer the energy.<br /><br />## Step 3<br />Sound travels faster in denser mediums. This is because the particles in a denser medium are closer together, which allows the energy to be transferred more quickly from one particle to another.
