Two choherent waves represented byy_1 = A sin ((2pi x_1)/(lamda) - wt + pi/3) " and " y_2 = A sin ((2pi x_2)/(lamda) - wt + pi/6) are superposed. The two waves will produce

Answer»

Constructive interference at `(x_1-x_2) = 2lamda`
Constructive interference at`(x_1 - x_2) = (23 lamda)/(24)`
DESTRUCTIVE interference at `(x_1 - x_2) = 1.5 lamda`
destructive interference `(x_1 - x_2) = (11 lamda)/(24)`
