Sound Lesson

Why is sound able to travel faster through a solid than a gas?

• Gas molecules are packed tightly.

• Sound does not travel faster through a solid than a gas.

• Solid molecules are packed tightly.

• Gas molecules move slowly.

A wave in which the vibration is in the same direction as that in which the wave is traveling; sound waves

• longitudinal wave

• ocean wave

• transverse wave

• mechanical wave

The part of a longitudinal wave where the particles of the medium are close together.

• rarefaction

• compression

• crest

• trough

A part in a longitudinal wave where the particles are spread apart

• compression

• rarefaction

Sound does not travel in space because

• Space is too far away.

• There is no matter in space.

• Space is the final frontier

• Space has planets.

• diffraction

• resonance

• loudness

• amplitude

What occurs when vibrations traveling through an object match the object's natural frequency?

• reflection

• diffraction

• resonance

• refraction
