we represent electromagnetic waves by sinosoidal curves.
magnitude of what changes sinosoidally?
or what does that represent?

Sinusoidal curves are mathematical representations of waves that follow the shape of a sine or cosine function. They are commonly used to describe various types of waves, such as sound waves and electromagnetic waves.
Sinusoidal curves are created by plotting the values of a sine or cosine function on a graph. The x-axis represents time or distance, while the y-axis represents the amplitude or height of the wave at that point in time or space.
The amplitude represents the maximum displacement of the wave from its equilibrium position. The frequency represents the number of cycles or oscillations that occur in a given time period. The phase shift represents the horizontal displacement of the wave from its original starting point. The vertical shift represents a constant value added to the entire curve, shifting it up or down.
Sinusoidal curves are used in various fields of science and engineering, such as acoustics, optics, and electronics. They are used to analyze and model different types of waves, such as sound waves, light waves, and radio waves. They are also used in applications like signal processing, communication systems, and medical imaging.
Harmonics are multiples of the fundamental frequency in a sinusoidal curve. They represent the different frequencies present in a complex wave. The shape of a sinusoidal curve is determined by the combination of these harmonics, with the fundamental frequency being the dominant component. In other words, sinusoidal curves are made up of a fundamental frequency and its harmonics.
