TYPES OF WAVES: -
Wave is a disturbance produced in a medium due to the repeated vibrations of the particles of the medium, about their equilibrium position.
There are mainly two types of waves that we are boardly find:
1) Longitudinal waves
1) Longitudinal waves
A wave, which propagates along the direction of vibration of the particles of the medium, is called longitudinal wave.
Sound waves are longitudinal in nature.
The regions where the molecules come closer are called compressions.
The regions where the molecules move apart are called rarefactions.
That is longitudinal waves propagate in the form of compressions and rarefactions.
2) Transverse wave
A wave, which propagates in a direction perpendicular to the direction of vibration of the particles of the medium, is called transverse wave.
Electromagnetic waves and vibrations in a string of a violin are transverse in nature.
The elevated portions of the string are called the crests and the depressed portions are called the troughs.
