Waves
Report Error
A
all the particles in the medium are in the same phase of vibration at all times and distances
17%
B
the particles with an interval between two consecutive nodes'are in phase, but the particles in two such consecutive intervals, are of opposite phase
17%
C
the phase lag along the path of the wave increases as the distance from the source increase
17%
D
only antinodes are in same phase
50%
Solution:
A stationary waves is formed when two waves of same frequency but travelling in apposite direction interfere.
