Question

Statement I: Velocity of particles, while crossing mean position (in stationary waves) varies from maximum at antinodes to zero at nodes.
Statement II: Amplitude of vibration at antinodes is maximum and at nodes, the amplitude is zero, and all particles between two successive nodes cross the mean position together.

• A. If both Statement I and Statement II are true and the Statement II is correct explanation of the Statement I
• B. If both Statement I and Statement II are true but the Statement II is not the correct explanation of the Statement II.
• C. If Statement I is true but Statement II is false
• D. If both the Statements are false.

Answer 1

Answer: (A)

Stationary wave

A node is a place of zero amplitude and an antinode is a place of maximum amplitude
