During propagation of longitudinal plane wave in a medium, two particles separat
During propagation of longitudinal plane wave in a medium, two particles separated by a distance equivalent to one wavelength at an instant will be/have
- A. In phase, same displacement
- B. In phase, different displacement
- C. Different phase, same displacement
- D. Different phase, different displacement
Step-by-step solution
Two particles separated by exactly one wavelength are at corresponding points on the wave cycle, meaning they have the same phase. In a sinusoidal longitudinal wave, points with the same phase also have identical displacement from equilibrium at any given instant.
