How does the Sun produce light and heat?The Sun is a medium-sized star among star categories. The solar system rotates around the sun. The sun is the primary source of light and heat for the Earth, responsible for maintaining the Earth's temperature within a reasonable range suitable for sustaining life. There has been considerable debate about the source of heat and light emitted by the sun. In the 1850s, scientists believed that when gravitational force was converted into thermal energy, light was produced. Some have suggested that when meteors fall on planets in the solar system, that is when light is produced. Later, theories developed in the light of modern technologies and as man moved closer to the sun, became capable of measuring changes occurring on the planet. surface of the sun. In the 1968s, scientists obtained enough evidence by capturing neutrinos from sunlight that the heat and light emitted by the sun are due to the nuclear reactions continuously taking place there. Before discussing the details of how light and heat are produced, the characteristics of the sun must be kept in mind. The body of the Sun is made of high-temperature hydrogen which can cause nuclear fusion. The fusion process requires two hydrogen atoms to fuse their nuclei and as a result a significant amount of energy is released in the form of light and heat which travels from the sun to the earth. Additionally, the fusion of two hydrogen nuclei results in the formation of helium. The fusion process is a never-ending process on the surface of the sun. On average, 120 million tons of mass composed primarily of hydrogen are converted to helium in 60 seconds. While some matter is also converted into energy (144). The energy emitted by...... middle of paper ...... in wavelengths of light that the human eye sees the rainbow that forms when light passes through the water droplets in the air. It then changes trajectory using the principles of refraction and lights of different wavelengths spin at a different angle. Besides the wavelengths of visible light, there are other wavelengths that our eye is unable to see. Infrared is an example of what can be felt by the skin. Infrared light causes the temperature of objects to increase. It is thanks to this particular wavelength that the rays cause the increase in the temperature of the earth and the atmosphere in general. Distribution of Energy in the Solar Spectrum Electromagnetic energy can be explained by treating the propagation of energy over a range of wavelengths. Radiation can be measured by finding the energy falling per second, or in watts per square meter for each 1 micrometer wavelength band..
