The Sun is the major source of light for the earth. The sun is a massive ball of fire, at the centre of which nuclear fusion produces massive energy. This energy comes out as heat and light.
30 paź 2024 · Sources of light are things that generate or reflect light such that they illuminate environments. This includes the Sun which is massively responsible for most light on our planet and across our solar system. There are also many natural and human-made sources of light.

The main source of natural light on Earth is the Sun. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight.
The sun is our planet’s major natural source of light. It radiates light and heat, which we use as energy. Plants use it to grow too! Stars create light via a process called nuclear fusion. Every second, a star is converting 4 million tons of its material into heat and light through nuclear fusion.
James Clerk Maxwell in his 1871 Theory of Heat outlines four stipulations for the definition of heat: It is something which may be transferred from one body to another, according to the second law of thermodynamics. It is a measurable quantity, and so can be treated mathematically.
