Here are the essential concepts you must grasp in order to answer the question correctly.
Standing Waves
A standing wave is formed by the interference of two traveling waves moving in opposite directions with the same frequency and amplitude. This results in a wave pattern that appears to be stationary, characterized by nodes (points of no displacement) and antinodes (points of maximum displacement). Understanding standing waves is crucial for analyzing their properties, such as amplitude and wavelength.

Amplitude
Amplitude refers to the maximum displacement of points on a wave from its rest position. In the context of standing waves, the amplitude of the wave function represents the maximum height of the wave at the antinodes. For a standing wave created by two equal traveling waves, the amplitude is effectively double that of the individual traveling waves.

Wave Function
The wave function describes the displacement of a wave as a function of position and time. In the given equation, y(x, t) = 4.44 mm sin[(32.5 rad/m)x] sin[(754 rad/s)t], the wave function combines spatial and temporal components, allowing us to analyze the wave's behavior. The coefficients and arguments of the sine functions provide information about the wave's amplitude, wavelength, and frequency.
