Question

Wavelength of the transverse wave is 30 cm.If the particle at some instant has displacement2 cm, find the displacement of the particle 15cm away at the same instant.(A) 2 cm(B) 17 cm(C) -2 cm(D) -17 cm​

Answer 1

Answer:

(c) -2 cm

Explanation:

15 cm denotes half the wave length.

thus the position is the same but on the negative axis. So the displacement is -2cm
