- Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum.

- How far does light go? how long does light go. - Jason (age 11) A: Hi Jason, Light just keeps going and going until it bumps into something.
- less than one photon? Can light intensity reduce to a level where it's energy is less than 1 photon (probably after travelling an almost infinite distance from a point source)?
- stars too far away to see? does there is any star that we can can't get it's light because of itis farness?...... sorry with having any problems in my English gramer, my English language is not good enough.
- light going out to space. If we are reflections of light, does that reflection make it out into space and keeps traveling til its asorbed.
Light is called an 'electromagnetic wave' for historical reasons* in the following sense: It turned out that the effects of visible light and other radiation can be calculated using Maxwell's equations, which are also used to model the behaviour of electrically charged particles. This was an instant of a successful unification and it hasn't ...
Currently light is thought of both as a wave and being made up of particles (photons), because as Robert mentioned in his answer, certain phenomena require modelling light as a wave to explain (interference, diffraction etc.), and others require photons (such as the photo-electric effect).
Apr 24, 2017 · Light always takes the shortest path between a source and destination. A line drawn from the source to the destination, perpendicular to the wave-fronts, is called a ray. Far from the source, spherical wave fronts degenerate into a series of parallel lines moving in the direction of the ray.
May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

Aug 26, 2022 · Beams of light are often described as having wavelengths, yet they are also described as being composed of particles called photons. Light is unique in that it can be described as both a wave and a particle. However, for reasons that remain unknown, you can never observe light as both a wave and a particle at the same time.
