INTERFERENCE OF WAVES

INTERFERENCE OF WAVES

1. MEANING :-

   • A phenomena in which 2 waves superpose = a resultant wave of greater / lower amplitude
   • superposition of two waves originating from two coherent sources.
     • COHERENT SOURCES
       • same frequency (f)
       • same wavelength
       • constant phase difference

2. HOW IT OCCURS ?

   • when two waves meet while propagating along the same medium.when two waves meet while propagating along the same medium.
   • (When the two waves = superposed) interference will occur either constructive interference / destructive interference.
     • CONSTRUCTIVE INTERFERENCE
     • DESTRUCTIVE INTERFERENCE

3. PRINCIPLE OF SUPERPOSITION OF WAVES :-

   • (When two waves interfered) the resulting displacement of the medium at any location
     • the algebraic sum of the displacements of the individual waves.
