WebProcedure: Take a few zinc granules in a conical flask. Add dilute HCl or H 2 SO 4 into the flask. Observe bubbles of hydrogen gas forming around the zinc granules. If a burning matchstick is brought near the mouth of the flask, then it burns with a pop sound, indicating the evolution of hydrogen gas. Chemical reaction: Zn + 2 HCl → ZnCl 2 + H 2. WebSound is a combination of low and high-pressure waves which is generated by a vibrating body. The vibration drives the particle in the propagation medium in vibrational motion, thus transmitting energy through the surrounding medium. 2) Sound waves are called mechanical waves. Why?

WebThe sound is a form of energy and is produced by vibrations. They are longitudinal and mechanical in nature. Sound waves can travel from one medium to another medium and when they do so there will be a change in speed and wavelength but not in frequency. Sound waves with the frequency in the range of (0-20 Hz) are called infrasonic waves. WebFree Online Kids PERFORM WITH MUSIC Trial Class. Age 6-18. Limited Spots Only. 1:1 Live Video Classes.
