When a light wave with a single frequency strikes an object, a number of things could happen. The light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object. Rarely however does just a single frequency of light ...
In absorption, the frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state. There are several options that could happen next, either the electron returns to the ground state emitting the photon of light or the energy ...
The absorbed energy is converted to heat energy. The scenario you mention with the LED is very close to the blackbody problem known as the "ultraviolet catastrophe." There is a Wikipedia article about it here. What happens in the situation you described is that the light proof box gets hotter. It will increase in heat until the heat leaving the ...
Jan 30, 2023 · The greater the frequency, the greater the energy. That's easy - but unfortunately UV-visible absorption spectra are always given using wavelengths of light rather than frequency. That means that you need to know the relationship between wavelength and frequency. You can see from this that the higher the frequency is, the lower the wavelength is.
Nov 21, 2021 · Transmission of light happens when light waves move all the way through a piece of material without being absorbed. Transmittance. When the light waves moves through a transparent (or semi-transparent) material, it can be either transmitted, absorbed, or reflected.
Light absorption is the process in which light is absorbed by matter and converted into energy. In an atom, electrons vibrate at a specific frequency – this is called the natural frequency. If a wave of light hits a material in which the electrons are vibrating at the same frequency as the wave of light, the electrons will absorb the energy ...

When light reaches a material, it can be absorbed, reflected, or transmitted. A material that doesn't transmit light is called opaque. An opaque object (e.g. a mug) does not let light through. An opaque material that reflects a lot of light has a lighter shade. An opaque material that reflects less light has a darker shade.
