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.

10 kwi 2024 · The source of solar power is energy carried by the electromagnetic waves radiated by the Sun. Most of this energy is carried by visible light and infrared (heat) radiation.
Heat is the flow of energy from one object to another. This flow of energy is caused by a difference in temperature. The transfer of heat can change temperature, as can work, another kind of energy transfer that is central to thermodynamics.
The basic unit of energy is the joule. One joule is the amount of work done when a force of 1 newton acts over a distance of 1 m; thus 1 J = 1 N-m. The newton is the amount of force required to accelerate a 1-kg mass by 1 m/sec 2, so the basic dimensions of the joule are kg m 2 s –2.
6 mar 2024 · Heat Definition. Heat is the thermal energy transfer between systems or bodies due to a temperature difference. Thermal energy, in turn, is the kinetic energy of vibrating and colliding particles. Heat occurs spontaneously from a hotter body to a colder one.
