Light does not carry any charge itself, so it does not attract or repel charged particles like electrons. Instead light is an oscillating electric and magnetic field. If you take an electron and put it in a static electric field (e.g. around a Van de Graaff Generator) then the electron feels a force due to the field and will move.
This is not a property of a wave. However when light hits a transparent object at a angle it will be refracted (except at 90 degrees). This is a property of a wave. Therefore light is seen as electric waves and magnetic waves oscillating at right angles from each other. Light is always either a wave or a particle but never both at the same time.
May 24, 2024 · Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other). Figure 2.1.1 – Electromagnetic Wave
It may be useful to start this explanation from the origin of a light wave: an oscillating charge. Start with the idea that a stationary charge is surrounded by an electric field, then imagine wiggling that charge up and down. Now the field lines will turn to wiggles instead of straight lines.
Dec 28, 2020 · This wave was predicted to move at the speed of light, and indeed turned out to actually be light! The Electromagnetic Spectrum Electromagnetic waves can come in many different wavelengths and frequencies, so long as the product of the wavelength and frequency of a given wave equals c , the speed of light.
Jul 27, 2023 · In general, the velocity of light is constant, c = 3.00 x 10 8 m/s. So for light, wavelength λ and frequency ν are related by \[c = \lambda ν\] Light is called electromagnetic radiation, which basically means that it radiates (travels) and the wave part is oscillating electric and magnetic fields. You don't need to worry about the details of ...

The speed of light in air is very close to 300 000 000 m/s. which is nearly a million times faster than the speed of sound, which is 340 m/s. 300 000 000 m/s is often written as 3 x \(10^8\) m/s.
