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.
1 day ago · Eighty-six years later, Heinrich Hertz became the first to demonstrate the particle nature of light. He noticed that when ultraviolet light shone on a metal surface, it generated a charge — a ...
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.
In 1678, Huygens proposed that every point that a luminous disturbance meets turns into a source of the spherical wave itself. The sum of the secondary waves, which are the result of the disturbance, determines what form the new wave will take. This theory of light is known as the ‘Huygens’ Principle’.

May 24, 2024 · The wave equation included physical constants from both electricity and magnetism, and extracting the wave speed from this equation resulted in a number Maxwell was already familiar with – the speed of light. It is traditional to denote this speed with a lower-case 'c': c = 3.0 ×108m s (2.1.1) (2.1.1) c = 3.0 × 10 8 m s.
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.

Einstein’s explanation. Einstein had a great explanation for this peculiar observation. He hypothesised light is made of particles, and is in fact not a wave. He then linked the intensity of light to the number of photons in a beam, and the frequency of light to how much energy each photon carries. When more photons are shot at the metal ...
