In a stationary wave,

1. Energy is constant

2. Maximum at node, minimum at antinode

3. Minimum at node, maximum at antinode

4. Oscillates between nodes

Which option is correct?

 

 

 

Dear student

At nodes pressure change (strain) is maximum .A node is a position of zero displacement andmaximum strain whereas an antinode is the position of maximumdisplacement and zero strain, The amplitude of vibration gradually increases from zero at node tomaximum at antinode.
