Question

what is vibration? what is periodic motion? what is medium? what does wave transfer? what is mechanical wave? ​

Answer 1

Explanation:

wave is a disturbance that transfers energy from one place to another without requiring any net flow of mass. For now, we'll focus on mechanical

waves, requiring a medium in which to travel. ... A pulse is a single disturbance while a periodic wave is a continually oscillating motion.

Answer 2

$\huge\boxed{\fcolorbox{white}{pink}{:) Periodic Motion :)}}$

We know that the motion moves round the earth.It takes about 30 days to make one complete revolution. This motion is then repeated and the process goes, 'on and on', month after month.

This type of motion, which repeats itself after a regular interval of time, is called a period motion.

Some examples of periodic motion are :-

• the motion of the earth as it revolves around the sun once every year.

• the motion of the hands of a clock.

Thus, A motion is said to be periodic if it repeats itself after a regular time interval.
