INTERFERENCE OF WAVES

INTERFERENCE OF WAVES

1. TYPES :-

   • destructive interference
     • Occurs when crest of one wave coincide with the trough of the other wave, thus canceling each other with the result = (resultant amplitude = 0)
   • constructive interference
     • Occurs when the crests or troughs of both waves coincide to produce a wave with crests and troughs of maximum amplitude.

2. YOUNG'S FORMULA :-

   • The relationship between λ, a, x and D

3. FACTORS AFFECTING THE INTERFERENCE PATTERN

   • The interference pattern depend on the value of x. (When x changes) the interference pattern also changes .
