(ii
(iii)
(iv)
The pairs of waves which will produce destructive interference and stationary waves respectively in a medium, are
A) (iii, iv), (i, ii)
B) (i, iii), (ii, iv)
C) (i, iv),(ii, iii)
D) (i, ii), (iii, iv)
Correct Answer: D
Solution :
| [d] In case of destructive interference |
Phase difference  or |
| So wave pair (i) and (ii) will produce destructive interference. |
| Stationary or standing waves will produce by equations (iii) & (iv) as two waves travelling along the same line but in opposite direction. |
