What is the other source of heat and light?

The sun is the main source of heat, warmth, and light for organisms living on Earth. Without the sun’s energy, Earth would be completely dark and freezing cold.

What is the source of heat and light of the sun?

The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun’s surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).

What are 3 source of heat?

In the end, if you’re wondering where the heat in your home comes from, it’s almost certainly one of the three main sources: combustion, electric resistance, or the outdoor air, ground, or water.

What are different sources of light?

Explanation: Natural sources of light include the sun, stars, fire, and electricity in storms. Flashlights, table lamps, neon signs, and televisions are some sources of artificial light. Most of the lights that are man-made need an energy source, such as electricity or batteries, to produce light.

Which is the main source of light on Earth?

Sources of light are things or devices that produce light, and the two general sources are natural and artificial. The sun is Earth’s main source of natural light that releases its energy as heat and light. This light is known as white light, and it is what gives Earth daylight.

Which is the natural source of heat energy?

Any object that can be used to derive heat is considered as a source of heat energy. There are many sources of heat energy. The sun is a part of our solar system. Thus, it is a natural source of heat energy.

What are the different types of heat energy?

The capacity of a physical system to perform work is called energy. There are different types of energy, such as heat energy, mechanical energy, light energy, sound energy and electric energy. Heat energy is produced when there is a transfer of heat from a warm object to a cool object.

How are heat, light, and sound related?

Heat, light, and sound are all forms of energy. Heat can be transferred by radiation, conduction and con- vection. Visible light can be produced, reflected, refracted, and separated into light of various colors. Sound is created by vibration and cannot travel through a vacuum.
