Define sound waves.
Sound waves are longitudinal mechanical waves that can be heard by the human ear.
It is a pattern of disturbance caused by the movement of energy travelling through a medium as it propagates away from the source of the sound.
The medium for sound waves includes air, water or any other liquid or solid matter.
What do we mean by a longitudinal mechanical wave?
Longitudinal mechanical waves are those in which particles of the medium (such as air, water, or solids) move parallel to the direction of the wave's propagation.
The following are characteristics of sound waves except?
Pitch
Loudness
Bass
Quality
Pitch can be described as ___
a measure of the complex nature of a sound wave
a measure of the frequency of a sound wave
a measure of the amplitude of a sound wave
a measure of the ratio of sound to the medium it travels through
Loudness can be described as ___
a measure of the ratio of sound to the medium it travels through
a measure of the frequency of a sound wave
a measure of the amplitude of a sound wave
a measure of the complex nature of a sound wave
