what is sound,what to we mean by Hertz
Answers
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain
Hertz is a measure of frequency. Specifically, it's one cycle per second. ... People with normal hearing can typically hear from about 50 Hz to about 20,000 hz (more typically 20 Khz). A 50 Hz sound would be like a low rumbling sound, and a 20 KHz sound would be very high frequency like the whooshing sounds of a cymbal.
hope you got that ....

Answer:
Sound is a vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.Sound travels fastest through solids as they molecules are tightly packed. Sound cannot travel in vacuum as they are no atoms or molecules tightly packed.It is basically a wave.In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain
Sound is calculated in Hertz.The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named after Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. Specifically, it's one cycle per second. ...
