Light is a form of energy, which can be emitted through a variety of processes. These processes include: Incandescence: The emission of light due to heat (as in an ordinary light bulb or a gas lantern) Fluorescence and phosphorescence: The emission of light in response to radiation energy (...
Light is a form of energy that can be released by an atom. It's made up of many small particle-like packets that have energy and momentum but no mass. These particles, called photons, are the most basic units of light. Photons are released as a result of moving electrons. In an atom...
Light is made up of photons, which are a form of energy. If you want to say that everything is made up of energy, that might be more correct. String theory claims that the universe is made up of incredibly small vibrating strings of energy. So one could say that vibration, not sound...
Energy from the sun is called solar energy(太阳能). It comes in the form of light or heat. People have used solar energy for thousands of years. The sun's energy can be used to heat water and even food.If you own a magnifying glass, your parents have probably warned you not to lea...
Light is a form of energy and can be changed from one form into another. Which materials let light through? An object that gives out light is described as luminous. How does light from a luminous object such as a light bulb reach the eye? How do we see things? An object that does ...
Light energy is the only form of energy that we can actually see directly. It is a type of kinetic energy, and it can also be converted into other forms of energy 反馈 收藏

Light is a form of electromagnetic irradiation whose energy causes responses in natural biological systems. Prominent examples are the photosynthesis in green plants, algae and some specific bacteria, in which the light energy is converted into chemical energy stored in organic compounds, or the synthe...
Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial ...
