Most Important Selected Qs for JEE AdvancedPhysicsWaves and Sound
The 5 graphs shown in column-II are plots of displacement from mean position at a given instant. The arrows represent the direction of velocity of particles at that moment. Match with description in column-I.
Options
- A(A) - (P, S), (B) - (Q, R), (C) - (T), (D) - (R)
- B(A) - (P, Q), (B) - (R, S), (C) - (T), (D) - (P, S, T)
- C(A) - (Q), (B) - (P, T), (C) - (S), (D) - (P, R, T)
- D(A) - (P, R), (B) - (S, T), (C) - (R), (D) - (P, Q)
Correct answer
B. (A) - (P, Q), (B) - (R, S), (C) - (T), (D) - (P, S, T)
Step-by-step solution
- For standing wave all particles have same direction of motion. - For longitudinal wave : Velocity of particle is along the propagation of wave.
