Answer:

${ \huge{ \boxed{ \fcolorbox{pink}{red}{Sound}}}}$

Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. If a sound wave is moving from left to right through air, then particles of air will be displaced both rightward and leftward as the energy of the sound wave passes through it.

There are various ways in which people participate in the process of government-

Through voting in elections People vote leaders of their choice to represent them. These representatives take decisions on behalf of their people.

People participate in the process of government by taking an interest in the working of government and by criticizing it when required.

People express their views through several ways and make governments understand what actions they should take. They stage dharnas, hold rallies, strikes, signature campaigns, etc.

Another ways for people to participate is by organizing themselves into social movements that seek to challenge the government and its functioning. Members of the minority community can participate in this manner.
