However, there are often obstructions. Coming from the center of the Sun, any photon would be certain to be absorbed by some atom within the Sun and then re-radiated a very great number of times before that packet of energy could reach the Sun's surface and be radiated into space. A neutrino, on the other hand, interacts with solid matter only very weakly. A neutrino generated within the Sun's core would probably pass directly through the mass of the Sun and escape into free space at nearly the speed of light.

Yuri Gagarin was the first human both sent to space and also to orbit the Earth.
What was the first toy on earth?
Marbles
When did the first dog come to earth?
They came from the eygt and dogs was the ruler of the egytians
Does energy from the sun reach earth by convection?
Simply put, there are 3 heat transmission phenomenons : convection, conduction and radiation. The first two are highly dependent of the nature of the material inbetween the two objects, which in this case is nothing at all. Waves, however, travel accross space and allow heat transmission by radiation.
What was the first 4d film?
journey to the centre of the earth
When an electron drops to a lower energy level what is the energy of the photon released?
The energy of the photon is the same as the energy lost by the electron
What is the wavelength of the photon emitted when a hydrogen atom goes from the second energy level to the first energy level?

What happens when the electrons return from the excited state to the ground state?
it looses energy , it gives off light in the form of a single photon.
What is first of the mainsources of energy for earth?
Hi, The first of the main sources of energy for earth is photosynthesis, and it is provided by the Sun.
What is the physical significance of planks constant?
Planck's Constant (abbreviated as 'h'), when first "discovered," was found to be the ratio of the energy of an individual photon to the frequency of that photon's light. In other words, the energy of a photon is equal to h times the photon's frequency. It has since been found that h fits into a wide variety of formula that allow us to understand the Universe we happen to live in. Without this constant, a lot of our Universe would be incomprehensible.

How is the Neutrino 3000 better than the Neutrino 2000 in Artemis Fowl?
The 3000 is powered by kinetics, is much lighter, and the first person to touch the gun becomes the owner of it.
What is gravitons?
Foundation of Graviton by regulating Photon; Neugravic Photon invented Inertial mass of neutrino is the origin of gravitational force. The quantum number of graviton ,1 , could be identified by changing the spin 1/2 to the one of anti-neutrino, of which interacting neutrons could emitting photons simultaneously. i-system's inner boundaries, which was condensed by inertial neutrino masses, oscillate particles up and down with a neugravic photon's process P, at temperature Ti and related frequency 1/T, P = 1/ ( exp((2h/4T)-mc2)/kTi) + Cos(2pi/T)t ) where, the total energy of neugravic photon 2h/T is divided within the quantum time period t=nT,(n+1/4)T,(n+1/2)T and (n+3/4)T. The velocity of photon is confined to c by the momentum remained to a neutrino's mass m within period. The i-system is condensed from the entropy expansion through the generation of n'th particles within different discrete times, t=nT; the n fermion's particle phase Cos(2pi)n=1, the mass of neutrino m=2h/4Tc2, P=1/2. t=(n+1/4)T and (n+3/4)T; each atomic neutrino's mass m=h/4Tc2, P= 1/exp(h/4TkTi). t=(n+1/2)T; P = 1/(exp(2h/4TkTi) - 1), m=0 for each boson. Two bosons' emitting energy is approaching to E=2h/T(x2-1) with a normalization; 1/2 = 2/x + 1/(x2-1), and t=(n+1/2)T is determined with temperature Ti; TTi~(8)(10Pr-12). The point fermion f at the first dimension of time t with mass m is divided to half fermion f' with x-dimension, atomic neutrino y dimension included and neugravic photon at all last dimensions. The Atomic Mass of space ship, 19tons, could go any place in uni- verse instantly to the nothern star y-direction of a neutrino condensed way, at now days t=(10Pr17) and at room temperature Ti=300, with our gravity floating of neugravic photon. *Answer: All atoms have at least one graviton particle in orbit around the nucleus. Gravitons have very large orbits and simply bump into atoms applying the force we call gravity. Most gravitons pass right through matter in the spaces between the atoms and only a fraction bump & apply a force. This same force also produces an effect known as inertia where objects are being bumped on all sides equally by gravitons, so resist movement, but once moving, are propelled by gravitons . An example of this are communication satellites which basically orbit the earth forever....A H Schrader December 2010
The line spectrum of lithium has a red line at 670.8 calculate the energy of a photon with its wavelength?
2.93x10^-19 Joules first use the v=c/h formula to find frequency then use the energy formula to find energy.
Does visible light have more or less energy than ultraviolet light?
Well, first of all, protons don't make light. I think you mean 'photons'. A photon of ultraviolet light carries more energy than a photon of visible light, because it has a higher frequency / shorter wavelength.
What is the point inside the earth where the first movement of an earthquake occurs and energy is released?
the point inside the earth where the first movement of an earthquake occurs and energy is released is called the epicenter.
