H.S. Level - SOund And Light Waves

H.S. Level - SOund And demoralise Waves Sounds are produced by the vibrations of sensible objects, and travel as a result of momentum transferee when air molecules collide. Our subjective impression approximately the frequency of a sound is called gear up. High pitch has high vibration frequency, succession low pitch has a low vibration frequency. A pure musical tone consists of a single pitch or frequency.

However, most musical tones are complex summations of unlike pure frequencies - one characteristic frequency, called the fundamental, and a series of overtones or harmonics Younger people can usually hear pitches with frequencies from about 20 hertz ( inaudible) to 20,000 (ultrasonic) hertz. We cant hear above 20,000 hertz or below 20 hertz (ultra and infrasonic waves). Light is both part particle and part wave. Light is the electromagnetic radiation that may be perceived by the human eye. It consists of photons, which are massless bundles of concentrated electromagnetic...If you want to notice a full essay, order it on our website: Orderessay
