Physics - Sound Wave Question with Solution | TestHub

When a string is stretched between two rigid supports, the displacement at the supports is always zero because the ends are fixed.

Thus, the ends of the string always act as nodes.

For the string to vibrate and form stationary waves, there must be at least one point of maximum displacement between the two fixed ends.

This point of maximum displacement is called an antinode.

Therefore, there are nodes at both ends and at least one antinode in between.

Answer: Nodes at both ends and at least one antinode in between
