Which type of radiation has the highest frequency?
Gamma rays
Is the sun radioactive?
Photons as light as well, yes? Definition of ‘radioactive’ according to Google: “emitting or relating to the emission of ionizing radiation or particles.” So, the sun emits ionizing particles, and is therefore radioactive.
What is the radiation from the sun?
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
How much radiation do I get from the sun?
The average annual dose or exposure from cosmic radiation is 0.33 mSv (33 mrem) or 11% of a person’s yearly exposure due to all natural sources of radiation. This yearly amount of radiation is similar to the amount of radiation from three chest x-rays.
Is the sun a proton?
The most abundant atom in the Sun is hydrogen. Each hydrogen atom is made up of a nucleus that contains a positively charged proton, and a remote, negatively charged electron that orbits the nucleus. In the Sun, collisions rip the hydrogen atoms apart, and separate the electron from the nucleus.
What happens when two protons collide in the sun?
Fusion in our Sun When two Hydrogen nuclei collide, one of the Protons undergoes a type of radioactive decay called Beta-plus Decay, where a proton transforms into a neutron. This happens when there are too many protons in the nucleus, because the positive protons repel each other.
How did the sun get its name?
The word sun comes from the Old English word sunne, which itself comes from the older Proto-Germanic language’s word sunnōn. During the reign of the Roman Empire, Helios was replaced with the Latin name Sol. Like Helios, Sol is a term that is still used to describe the Sun.
How long does a hydrogen atom live?
Ultimately, even these stable atoms have a limit imposed by the lifetime of proton (>1025 years). Remember, though, that the best estimate of the present age of the universe is the much smaller number of 1010 years, so for all practical purposes, atoms are forever.
Can a hydrogen atom decay?
To the best of our knowledge, an isolated proton, a hydrogen nucleus with or without an electron, does not decay. An isolated neutron is unstable and will decay with a half-life of 10.5 minutes. A neutron in a nucleus will decay if a more stable nucleus results; the half-life of the decay depends on the isotope.
Do all atoms eventually decay?
No. Stable atoms do not decay. The only problem is that it is very difficult to tell whether a particular isotope is stable or just extremely long at decaying.
How much energy is in a hydrogen atom?
The energy equivalent of a hydrogen atom is 0.16*10-9 joules or 0.16 billionths of a joule.
Does the proton decay?
[+] To the best of our understanding, the proton is a truly stable particle, and has never been observed to decay. Because of the various conservation laws of particle physics, a proton can only decay into lighter particles than itself. It cannot decay into a neutron or any other combination of three quarks.
