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.

Track and visualize how energy flows and changes through your system. Explore how heating and cooling iron, brick, water, and olive oil adds or removes energy. See how energy is transferred between objects.
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.
We will follow this general procedure in this lab to measure the specific heat of an unknown substance and identify the substance by comparing the specific heat to a table of specific heats. A word of caution is appropriate here. We will use mercury-filled thermometers to measure temperatures.
a light source. Random (incoherent) light sources, such as stars and light bulbs, emit photons with random arrival times and a Bose-Einstein distribution. Laser (coherent) light sources, on the other hand, have a more uniform (but still random) distribution: Poisson.
Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
The result of the movement of minute particles known as atoms, molecules, or ions in liquids, solids, and gases is nothing but heat energy. Heat energy can be transferred from one substance to another, and the flow because of the temperature difference between two objects is known as heat.
