Four waves are represented by y1 = A1 sin pt,
y2 = A2 sin (pt + p/2), y3 = A1 sin (2pt + p/2) and y4 = A2 sin (pt – p/3). Interference will happen with –
A
y1, y2 and y3 only
B
y1, y2 and y4 only
C
y1 and y3 only
D
y1, y2, y3 and y4
Answer
y1, y2, y3 and y4
Explanation
Solution
Interference is phenomena of more than one wave reaching at same point in space simultaneously.
