Mar 31, 2015 · In light propagation, oscillation does not mean any movement in space. It is the value of the electromagnetic field, at one given point in space, that oscillates. The picture that you quote does not represent the movement in space, but the electromagnetic field value as a function of time.

This is exactly what happens in your TV aerial. The light (i.e. radio frequency EM) causes electrons in the TV aerial to oscillate and this oscillation generates an oscillating electric current. The voltage this generates is amplified by your TV.
Here is the simple explanation as to why electromagnetic waves oscillate. As you probably already know, electromagnetic waves are generated by moving electrons. An electron generates an electric field.
In fact, this gives us a way of describing how the wave propagates: The wave causes a single point to oscillate, which in turn causes a wave to be generated, which then vibrates another point, and so on.
Jan 19, 2023 · For visible light the charges have to be oscillating back-and-forth around 10 14 times per second. For objects at room temperature (around 300K) the oscillating atoms give off electromagnetic light at roughly 10 13 Hz. This light is called infrared, because its frequency is closest to red in visible light. While people cannot see this light ...
Apr 10, 2022 · Describe the relationship between wavelength, frequency, and speed of light. Discuss the particle model of light and the definition of photon. Explain how and why the amount of light we see from an object depends upon its distance.

Aug 10, 2024 · These waves are produced when wind, a stone, or some other disturbance, such as a passing boat, transfers energy to the water, causing the surface to oscillate up and down as the energy travels outward from its point of origin. As a wave passes a particular point on the surface of the water, anything floating there moves up and down.
