Explanation:
a) amplitude- the maximum displacement of a vibrating body in a central position,is called amplitude. its SI unit is metre. ... its SI unit is second. c) frequency -a vibrating body completes its fixed number of cycles of vibration is one second,is called frequency. its SI unit is hertz.
Answer:
Frequency in a sound wave refers to the rate of the vibration of the sound travelling through the air. This parameter decides whether a sound is perceived as high pitched or low pitched. In sound, the frequency is also known as Pitch. The frequency of the vibrating source of sound is calculated in cycles per second.
The SI Unit for Frequency being hertz and its definition being ‘1/T’ where T refers to the time period of the wave. The time period is the time required for the wave to complete one cycle. Wavelength and frequency of a sound wave are related mathematically as:
The velocity of Sound = Frequency * Wavelength
The below graphs can be used for understanding more about sound. The first graph represents a sound wave from a drum while the second graph represents the sound wave from a whistle. You probably already know the difference in the sounds but have a look at the difference in their frequencies.
