Question

I. In a standing wave, the disturbance produced is confined to the region where it is produced. II. In a standing wave, all the particles cross their mean position together. III. In a standing wave, energy is transmitted from one region of space to other. IV. All the particles are oscillating with same amplitude. Which of the given statement(s) is/are correct about the standing wave? (A) Both I and II (B) Both II and IV (C) Only III (D) I, II, III and IV

Statements I and II are correct but III and IV are incorrect and these can be corrected as, In a standing wave, the disturbance produced and the energy of one region remains confined to that region only. Amplitude of all particles is different at different position. It means, it varies from point-to-point.
