Webb7 okt. 2024 · Photosphere This is the visible ‘surface’ of the Sun. Almost all radiation from the Sun is emitted from this thin layer of several 100 km thickness, which lies at the upper boundary of the convection zone. It is … Webb23 sep. 2024 · The Sun. The Sun is a star, just like the ones you can see in the night sky, but much, much, much closer. In fact, our Sun is a rather ordinary star – it's not particularly big or particularly small, it's not …

WebbSecond, there is at least one element that was first discovered by it's absorption lines in the solar spectrum: helium (named for the Greek god of the sun, Helios), so we can be confident that the measurements we're making correspond to physical reality. Third, we have performed measurements using satellites that are above the atmosphere. WebbBefore the invention of the telescope, the Sun was thought to be an unchanging and perfect sphere. We now know that the Sun is in a perpetual state of change: its surface is a … how do i set up my ovo online account

Webb2 feb. 2024 · There are two things in effect here: the sun's atmosphere and the earth's atmosphere. The sun's appearance is determined by the structure of its atmosphere, which consists of the photosphere (average color temperature of around 5800K, i.e. what we perceive as pure neutral white), the chromosphere that is above it (which appears red) … Webb1. In the upper photosphere, the electrons join with the ions to neutralize the atom. When a photon strikes this atom (the atom absorbs the photon), it promotes a electron from a low energy shell to an higher energy shell. The electron then falls back to the lower energy shell emitting a photon in a different direction. WebbScience Physics If a sunspot has a temperature of 4,270 K and the average solar photosphere has a temperature of 5,780 K, how many times more energy is emitted in 1 second from a square meter of the photosphere compared to a square meter of the sunspot? (Hint: Use the Stefan-Boltzmann law, E = σT4 (J/s/m2) where E is the energy, σ … how do i set up my new iphone 13
