Wave motion Short Questions and answers

                 Wave Motions

-WAVE :

            Wave is the disturbance produced in the medium due to repeated periodic vibrations of particle of the medium, about their equilibrium position. There are 2 types of waves,

1) Mechanical / Elastic wave

2) Non-mechanical / Electro-magnetic wave

-WAVE MOTION :

             The wave motion is the form of disturbance which travels through a medium due to repeated periodic motion of the particle of the medium about their equilibrium position.

-CREST :

           The maximum displacement of the particle of the medium above the equilibrium position is called crest.

-Trough :

      The maximum displacement of the particle of the medium below the equilibrium position is called trough.

-AMPLITUDE:

        The maximum displacement os the medium from its equilibrium state is called amplitude.

- WAVE LENGTH :

      The distance traveled by the wave during the time at which any particle of the medium completes one vibration about its mean position is called wave length. It is denoted by "λ" .

-FREQUENCY :

       The number of oscillation completed by the particle of the medium in 1 second is called frequency. It is denoted by "f".

-Time Period :

      It is defined as the time taken by the vibrating particle in the medium to complete one oscillation. It is denoted by "T" .

- WAVE VELOCITY ;

        The distance traveled by the wave in 1 second is called wave velocity. It is denoted by "v".

- PHASE :

       The state of motion as the particle means where is the particle and what its direction of motion.
