Dec 12, 2022 · It takes approximately 8-minutes for sunlight to reach Earth. The Earth orbits the sun at an average distance of 93-million miles (150-million kilometres). At this distance, there is a noticeable delay in when light emitted by the sun reaches our world. In fact, just by knowing the speed of light and the distance between the sun and Earth, you ...
Mar 13, 2018 · When light travels through space from the sun, all of the frequencies of light travel in a straight line. When light hits the atmosphere, however, the photons begin to collide with gas molecules. Red, orange and yellow photons have long wavelengths and can travel right through the gas molecules. Green, blue and purple photons, however, have ...
Oct 4, 2012 · An elegant interaction powers the sun, producing the light and energy that makes life possible. That interaction is called fusion, and it naturally occurs when two atoms are heated and compressed so intensely that their nuclei merge into a new element. This process often leads to the creation of a photon, the particles of light that are released from the sun. However, before exiting our star ...
Aug 23, 2023 · The sun warms our planet, provides us with light and is crucial to all life on Earth. DrPixel / Getty Images. When’s the last time you gazed upward and marveled at the mysterious, life-giving force that is the sun?. If you believe the whole staring-at-the-sun-makes-you-go-blind thing (which is actually true), you’re probably not doing a whole lot of sun-gazing. But it’s a real marvel ...
There are two main types of energy that come from the Sun. These include visible radiation, which we perceive as light, and invisible infrared energy, which we sometimes think of as heat. Both visible and infrared radiation are part of the electromagnetic spectrum, which includes all the types of energy released by the Sun.
Nov 5, 2020 · The light from the Sun comes from the photosphere; a relatively thin layer, a few hundred km thick. The photosphere of the Sun is in radiative equilibrium, getting neither hotter or colder on average.

The Sun’s Energy is Important to Life on Earth. Energy from the Sun makes it possible for life to exist on Earth. It is responsible for photosynthesis in plants, vision in animals, and many other natural processes, such as the movements of air and water that create weather. Most plants need at least some sunlight to grow, so without light ...
