Why are why are most of the waves that hit earth UV rays visible rays and infrared rays?

Answer 1

Let's start from the beginning. The energy produced by the Sun comes from the nuclear process known as fusion, which, in the case of our Sun, ultimately converts hydrogen into helium. This conversion cycle, however, is not just that one simple step. Many different intermediate fusion processes occur, and each one releases some energy in the form of a high-energy photon, called a gamma ray.

At this point, it's crucial to know that all of these fusion processes, and therefore all of the gamma rays produced from them, occur within the inner 25% of the Sun's volume. It's also crucial to know that the Sun is very large (roughly 1.3 milliontimes larger than the Earth) and very dense (1.6 X 105 kg/m3 at the core and gradually decreasing as you move towards the surface). Therefore, the gamma rays produced in the fusion process take tens of thousands of years before they can finally escape out into space. For the duration that these gamma rays are "trapped" inside the Sun, they constantly scatter off other particles, and every time they do so, they lose a little bit of energy. That translates into them becoming lower and lower in frequency and having longer and longer wavelengths. By the time they finally reach the point where they can "escape" from the Sun, their energy, and thus their frequency, has dropped to the visible light and infrared region of the electromagnetic spectrum (some escape as ultraviolet radiation as well). So, that's why we see mostly those types of EM waves down here on Earth, because they're the only ones that escape.

Answer 2

The atmosphere only lets specific types of light through - mainly visible light (and frequencies near the visible light), and radio waves.

Also, due to its temperature, the Sun produces mainly visible light.

Answer 3

Each type of electromagnetic radiation is produced by a certain temperature range. Only very hot objects emit visible light or ultraviolet light; the sun is that hot, but the Earth (mostly) isn't. At the temperature range of the planet Earth, infrared rays are produced. apexs suxks

Answer 4

most of the energy emitted by the sun is in the form of ultraviolet,visible, and infrared waves. these waves carry energy away from the sun and spread it out in all directions.

Answer 5

Most of the energy emitted by the sun is in the form of ultraviolet,visible, and infrared waves. These waves carry energy away from the sun and spread it out in all directions.

Answer 6

The sun radiation energy level is higher than the earth, thus E=hf is higher for the sun, thus the sun's frequency f is higher and includes the visible and higher radiation.

Answer 7

UV are able to reach the earth. it is because of the ozone hole that is present.
