Unit 2 Sound

The vertical distance between a crest or trough and the resting position. measures the loudness of a sound.

• pitch

• amplitude

• frequency

• rarefaction

This type of wave travels in the same direction as the energy is moving. Sound travels this way.

• transverse wave

• longitudinal wave

• pitch

• medium

An area of less tightly packed particles caused by the motion of sound.

• compression

• medium

• rarefaction

• longitudinal wave

An area of tightly packed particles caused by a sound wave is (a)   .

This type of wave travels perpendicular to the direction of the movement of energy. Light travels this way.

• transverse wave

• longitudinal wave

Matter needed for sound to travel through, that can be in the form of a solid, liquid or gas is called (a)   .

(a)   is how low or high a sound is.

The number of wave cycles passing a point per unit time. In sound, this measures the PITCH of sound.

• trough

• crest

• frequency

• rarefaction

(a)   is the lowest point a wave or graph sinks to.
