Sound waves can be seen on an instrument called an Oscilloscope. The idea behind sound waves is that noise emits tine waves that we pick up on. the distance between each wave (called a crest) is wavelength. frequency is the number of waves that pass a point each second. Amplitude is the measure of energy in a sound wave. Sound waves are more easily graphed through trig, as sine and cosine produce graphs in these waves. The higher the intensity of the sound, the bigger the wave is. Sound, like light, takes time to travel. the further distance you are from a sound, the longer it takes to reach you. even when sound is matching up perfectly with what you see, the sounds you hear are reaching your ears at a slower rate. pleasant sounds tend to have a repeating wave, while noise will be extremely erratic and strange looking. Sound is a pressure wave, which actually moves the particles in the air around it back and forth.
