Question

In which kind of wave is the amplitude at each point constant?

a) Transverse wave

b) Longitudinal wave

c) Standing wave

d) Seismic wave

Answer 1

In a standing wave, amplitude is constant at each point, with nodes having zero amplitude and antinodes having the maximum, which distinguishes it from transverse, longitudinal, and seismic waves.

Step-by-step explanation:

The type of wave where the amplitude at each point is constant is a standing wave. In a standing wave, points known as nodes have a zero amplitude, and the points in between nodes, called antinodes, have the maximum amplitude. Unlike transverse waves, longitudinal waves, and seismic waves, which have amplitudes that vary as the wave travels through a medium, a standing wave's amplitude is fixed at each point along the medium.
