Actual shape of electromagnetic waves - Physics Stack Exchange
2021年2月19日 · Let us say the blue sine wave is showing the strength (lengths of the arrows) and the direction of electric field at the point on the line of propagation. This point is actually on the line labeled Z. Similarly the red sine wave shows the strength (lengths of the arrows) and the direction of magnetic field at the point on the line of propagation.
Sine wave - Wikipedia
Tracing the y component of a circle while going around the circle results in a sine wave (red). Tracing the x component results in a cosine wave (blue). Both waves are sinusoids of the same frequency but different phases. A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine ...

2022年5月22日 · To the left (red) is a wave leading the initial wave by one-eighth cycle, or 45\(^{\circ}\). To the right (blue), is a lagging wave of half as much, or −22.5\(^{\circ}\). Figure \(\PageIndex{6}\): Sine wave phase variation. Combining the foregoing elements allows us to develop a general format for a sine wave (voltage shown):

Lecture 3 - How the Fourier Transform Works
When thinking about sound signals, especially when used in music, we tend to think only of frequency or pitch and amplitude or how loud it is. However, there is a 3rd property of a sine wave that can be changed and that is its phase. To demonstrate what phase is, let’s take a Sine wave.
Two-Slit Wave Model - Exploratorium
The red light waves will be longer than the blue. You have made a good model of red and blue light waves. Look at any sine-wave card and notice three important points: the maximum (highest point), the zero crossings (where the wave crosses the middle line of the card, including at the leading and trailing edges), and the minimum (lowest point).

Sinusoidal Waves Explained Simply - Andrea Minini
For instance, let’s compare two sinusoidal waves: The red wave completes ω = 2 cycles per second, while the blue wave completes ω = 4 cycles per second. As a result, the blue wave has a higher angular frequency than the red wave (ω*>ω). …
