REFLECTION OF WAVES

REFLECTION OF WAVES

1. LAW OF REFLECTION :-

   • The angle of incidence, i = the angle of reflection, r.

2. TYPES OF WAVE :-

   • incident wave
     • the wave before it strikes the obstacle
   • reflected wave
     • the wave which has undergone a change in direction of propagation after reflection.
     • i = angle of incident – the angle between the direction of propagation of incident wave and the normal
     • r = angle of reflection – the angle between the direction of propagation

3. MEANING :-

   • Occurs when a wave strikes an obstacle.
   • The wave undergoes a change in direction of propagation when it is reflected.
   • The value of frequency (f), wavelength (λ) & speed (v) remain the same after reflection.
