The image displays a mathematical graph plotted on a plain white background. Two thin, light gray lines form the coordinate axes: a vertical y-axis running up the left side and a horizontal x-axis extending across the middle of the frame. They intersect at the bottom left corner to form an origin point.

A thick, solid black line represents a wave function, specifically resembling a sine wave. The line begins exactly at the intersection of the two axes. It curves smoothly upward and to the right, forming a rounded peak in the upper left quadrant. After reaching its maximum height, the line descends, crossing the horizontal axis near the center of the image.

Continuing downward into the lower right area, the line forms an inverted curve or trough, reaching
