Characteristics of a sound wave, Frequency, Amplitude, speed, Time period
Characteristics of a sound wave There are many characteristics of sound wave. (1) Frequency (2) Speed (3) amplitude Distinguish between loudness and intensity of sound (1) Loudness is a measure of the response of the ear to the sound. Intensity is the amount of sound energy passing each second through unit area. (2) Loudness is measured in decibels (db). Whereas intensity is measured in watt per meter square (W/m 2 ). (3) Loudness is a subjective quantity. Intensity is an objective quantity. (4) Loudness depends on Amplitude. Intensity depends on the Frequency and the Am...
