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
