Photons take longer to emerge from the sun compared to neutrinos because they interact more frequently with the sun's dense matter, causing them to be absorbed and re-emitted multiple times before finally escaping. Neutrinos, on the other hand, hardly interact with matter and can easily pass through the sun, allowing them to emerge much faster.
Yes, neutrinos are subatomic particles with a very small, non-zero mass. They are much larger than the Planck length, which is the scale at which quantum effects of gravity become important.
A microwave signal at 50 GHz has waves that are 10,000 times as long as a visible signal at yellow (600 nm) has. Therefore the yellow photon carries 10,000 times as much energy as the 50 GHz photon does.
Yes, light exhibits characteristics of both photons and waves. It can behave as a stream of particles (photons) when interacting with matter, while also exhibiting wave-like properties such as interference and diffraction. This duality is known as the wave-particle duality of light.
In annihilation between electron and positron, you should get nothing in your hand. Instead of that you get a pair of photons. The question is that why should you get the pair of photons. So this is not complete annihilation. The answer is simple to this question. When you bring the electron and positron slowly to each other, they will annihilate to each other and will not produce the photons also. But when the particles come with high speed, they carry the energy and have momentum. This energy is converted into photons of different wave length and the electron and positron disappear or get completely annihilated. When you have heavy particles like protons and anti-protons or neutrons and anti-neutrons strike to each other, you get much larger amount of energy that is left. Because they are brought to each other at high speed, they have high momentum and so carry the large amount of energy. This energy is liberated after the annihilation. When enough quantum of energy is there, you have production of electrons, positrons and neutrinos get generated. The rest of the energy is left in the form of photons. When larger molecules of matter and antimatter will collide with each other, you may get smaller molecules of matter and antimatter in your hand.
The energy of a photon of ultraviolet radiation is greater than the energy of an average photon of sunlight because ultraviolet radiation has higher frequencies and shorter wavelengths, which correspond to higher energy photons. The difference in energy can be significant, with ultraviolet photons having several times more energy than photons of sunlight.
Some recent experiments (2010 and 2011) suggested that neutrinos might be massless and travel very slightly faster than the speed of light (0.003 %). However, these are at odds with measurements that show neutrinos and light photons travelling at roughly the same speed. Further experiments are planned to test how photons and neutrinos are affected by the medium they traverse. If neutrinos do have mass, by the theory of relativity they cannot reach or exceed light speed.
Neutrinos are elementary particles that travel close to the speed of light, lack an electric charge, are able to pass through ordinary matter almost undisturbed and are thus extremely difficult to detect. Neutrinos have a minuscule, but non-zero, mass that was too small to be measured as of 2007.
Hardly, since the hardly ever interact with matter, and don't have much energy.
Yes, neutrinos are subatomic particles with a very small, non-zero mass. They are much larger than the Planck length, which is the scale at which quantum effects of gravity become important.
Yes but not at much high level
A microwave signal at 50 GHz has waves that are 10,000 times as long as a visible signal at yellow (600 nm) has. Therefore the yellow photon carries 10,000 times as much energy as the 50 GHz photon does.
I very much doubt it.We are bombarded by neutrinos from the Sun every second.It has been estimated that more than 50 trillion neutrinos pass through the human body every second. - that's one good shower.
Much longer
As much as 50% of energy produced in reactions between nucleons and antinucleons is carried away by neutrinos in these applications. It is theoretically possible to retain as much as 100% of the energy in an Antimatter reaction.
Yes, gamma radiation is rays. Specifically it is photons, like light but much much higher in energy.
Dark matter MIGHT be made of neutrinos. Problem is, we can't be certain because of two gaps in our knowledge: 1) how much mass is in one neutrino? We have an upper limit for its mass (about 1 eV) and we have a lower limit for its mass (about 0.04 eV); but we don't know any better than that. 2) how many neutrinos are out there? We can make a general estimate of how many neutrinos existed near the start of the Big Bang, but even this has some variation. Then we must ask what percentage of neutrinos have decayed in the last 13.7 billion years. Again, we know that neutrinos decay, but we don't have a good idea of how often they do so. As we get a better idea of the answer to (1) and (2), we might be able to either conclude that neutrinos account for almost all of the dark matter, or that they account for very little. Until then, we're just multiplying a speculative number times a speculative number times a speculative number.
