Answer #1

a)

For a standing wave, the amplitudes of the particles along the wave are not equal.

Nodes are the points for which the amplitude is zero. The displacement of nodes is zero all the time. These points are not physically clamped but they remain fixed.

Antinodes are the points of maximum amplitude. The displacement of antinode increases from 0 to maximum with time and and is in phase with other antinodes.

b)

The distance between two consecutive nodes = 1/2 of the wavelength of the standing wave.

c)
