Final answer:
In a full wavelength of a standing wave, there is an integer number plus one of the nodes at stationary points, with antinodes being at points of maximum amplitude between them.
Step-by-step explanation:
The total number of nodes and antinodes along one full wavelength of a standing wave can be determined based on the formation of standing waves. In one full wavelength, there is always an integer number plus one of the nodes due to the requirement for nodes to be at the ends of the wavelengths at stationary points.
Similarly, the antinodes, which are the points of maximum amplitude, are situated between the nodes. For example, in a single wavelength, you might have two nodes at the ends and one antinode between them, or you might have more, like three nodes with two antinodes in between, depending on the number of wavelengths contained within the string or another medium.
