Charactaristics of a Soundwave
Wavelength; this is the
distance from the crest of one wave to the crest of the next.
Frequency; this is the number
of waves that pass a point in each second.
Amplitude; this is the measure
of the amount of energy in a sound wave.

There are so many different types of sound waves as well. Many differences that, not only define the type of soundwave, but changes the shape of the sound wave. Things like...
Pitch This is how high or low a sound seems. A bird makes a high pitch. A bass drum makes a low pitch. Sounds also are different in how loud and how soft they are. The more energy the sound wave has the louder the sound seems. The intensity of a sound is the amount of energy it has. You hear intensity as loudness. Loudness also increases the size of the sound wave. Pitch and loudness are two ways that sounds are different. Another way is in quality. Some sounds are pleasant and some are a noise. Compare the two waves on the right. A pleasant sound has a regular wave pattern. The pattern is repeated over and over. But the waves of noise are irregular. They do not have a repeated pattern. |
