please mark as branliest

Answer 2

1.sound

2.wave

3.to and fro

4. Vibratory

5.hertz

6.amplitude

-Vibrating objects do not produce Sound. All vibrating objects produce vibration in the form of molecules of the medium, so all Vibrating objects can produce vibrations.

-sound produce in form of mechanical waves. A mechanical wave is a disturbance that causes and helps in transporting energy from one medium to another medium.

-Sound travels in a longitudinal wave, in which the particles oscillate to and fro motion in the same direction of wave propagation.

-Sound waves are vibratory in nature because sound travels in waves.

-The SI unit of frequency is hertz.

- loudness of a sound depends on the amplitude of sound waves.
