Figure shows a rectangular pulse and a triangular pulse approaching each other along x-axis. The pulse speed is 0.5 cm/s. What is the resultant displacement of medium particles due to superposition of waves at x = 0.5 cm and
t = 2 sec.
A
(a) 3.5 cm
A
(b) 2.5 cm
A
(c) 4 cm
A
(d) 3 cm
Explanation
Solution
(d)
x1 = 0.5 × t = 0.5 × 2 = 1cm
x2 = 0.5 × t = 0.5 × 2 = 1cm
at t = 2 sec
at x = 0.5 cm, y = 3 cm
