some amazing facts about waves are as follow:

WAVES

def;
The transmission of energy in a medium due to the oscillatory motion of the particla of the medium about their mean position is called "wave motion " 

Example :
some common example of waves are following :
1 : sound of school bell 
2 : transmition of radio program from radio station 

Types of waves :
Their are two typpes 

1) Longitudnal Waves

2)Tranverse Wave

 

Transverse Wave:

Def

The waves in which the vibration of a indiviusal particle medium is prependicular to the direction of propagation of waves are called tranverse waves '

 

Explanation:

THE waves produces by moving one end of stressed string up and down are also: transverse waves because different parts of a string vibrate prependicular to the direction of  propagation of waves 

Examples :

examples of tranverse waves are following

1) Electromegnatic waves  or  radio waves

2)X-Rays

3) Television waves

4) Heat and Light waves

 

Longitudnal Waves :

Def;

 The waves in which the particles of medium move about its mean position parallel to the direction of  propagation of waves  are called  Longitudnal Waves.

Explannation:

since in the air molecules are dispersed  forwad and backward on the same axis along the axis which the sound travel.

Examples:

examples of longitudnal waves are as follow:

1 )Sound waves i-e guitar sound , t.v sound or radio sound
