alleryStart learning →In a standing wave, what is an antinode?
AThe location of maximum amplitude
BThe location of zero disturbance
CThe point where the string is tied
DThe distance between two nodes
Answer & Solution
Correct answer: A. The location of maximum amplitude
1. An antinode is the location of maximum amplitude in a standing wave.
2. It sits midway between neighbouring nodes, where the disturbance stays zero.
3. Zero disturbance describes a node, so that option names the opposite feature.
4. Tied ends of a string cannot move, so they are nodes rather than antinodes.
