What is the range of wavelengths for visible light?
380 to 700 nanometers
How much greater is the light collecting area of a 4 m telescope than that of a 1m telescope?
A telescope with a mirror that is 4 meters in diameter can collect 16 times as much light as a telescope that is 1 meter in diameter.
How does the wavelength of light depend on the amplitude?
How does the wavelength of the light depend on the amplitude? It does not depend on it. The wavelength (color) and frequency of the light do not depend on the amplitude. Blue light and red light have the same speed.
Under what circumstances can energy level transitions occur under what circumstances can energy level transitions occur electrons can make a transition from one level to another by taking in or emitting a specific amount of energy if too much or too little energy?
Electrons can make a transition from one level to another by taking in or emitting a specific amount of energy. If too much or too little energy is offered, the electron cannot make the transition. it reflects green light and absorbs other colors.
What happens to photons when they are absorbed?
The simplest answer is that when a photon is absorbed by an electron, it is completely destroyed. All its energy is imparted to the electron, which instantly jumps to a new energy level. The photon itself ceases to be. The opposite happens when an electron emits a photon.
What happens when an electron emits a photon?
When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. Electrons therefore have to jump around within the atom as they either gain or lose energy.
Why do electrons give off photons?
The electron stays in an excited state for a short time. When the electron transits from an excited state to its lower energy state, it will gice off the same amound of energy needed to raise to that level. This emitted energy is a photon.
How many photons can an electron absorb?
one photon
What is the relationship between photons and electrons?
Photons are neutrally charged, massless particles that make up light. Electrons are negatively charged, massive particles that are usually found swarming around the nuclei of atoms. Electricity is caused by the flow of electrons from one point to another.
How do you convert photons to electrons?
Photovoltaics turn photons into electrons by what is called the “photovoltaic” effect, (photo meaning light, and voltaic meaning electricity). In the photovoltaic effect, rays of photons in the sunlight strike the surface of the silicon semiconductor material liberating free electrons from the materials atoms.
What do electrons and light have in common?
Electrons and light have in common that they can both be expressed as waves or as a particle which is known as duality.
Are photons smaller than electrons?
That’s certainly small but not smaller then a photons which don’t have any mass, charge and radius. the size of photons and electrons are same as mass,but electron is negatively charged particle and photon is the energy (quanta).
Do photons have a size?
While photons don’t have a physical diameter, and can be treated as point particles, their quantum behavior gives them a probabilistic size. As a photon gets closer to another object, the chance of it interacting becomes greater. Under this definition there is no absolute “size” to a photon.
Is anything smaller than a photon?
nothing is smaller than a photon. It has no matter. we can’t see a photon. It has no matter.
Are photons smaller than an atom?
A Photon is the Quantum of Electromagnetic Radiation while an atom is the fundamental constituent of all the Matter. Its size may be similar to the size of subatomic particles like Electron but it’s smaller than an atom.
What is inside a photon?
A photon is massless, has no electric charge, and is a stable particle. In a vacuum, a photon has two possible polarization states. The photon is the gauge boson for electromagnetism, and therefore all other quantum numbers of the photon (such as lepton number, baryon number, and flavour quantum numbers) are zero.
What is inside a quark?
A quark (/kwɔːrk, kwɑːrk/) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. Up and down quarks have the lowest masses of all quarks.
What is smaller than a God particle?
The so-called techni-quarks can be the yet unseen particles, smaller than the Higgs particle that will form a natural extension of the Standard Model which includes three generations of quarks and leptons.
Is anything smaller than a quark?
In particle physics, preons are point particles, conceived of as sub-components of quarks and leptons. Each of the preon models postulates a set of fewer fundamental particles than those of the Standard Model, together with the rules governing how those fundamental particles combine and interact.
Can you split a quark?
Quarks,and leptons are thought to be elementary particles, that is they have no substructure. So you cannot split them. Quarks are fundamental particles and cannot be split.
Does a quark have mass?
Quarks have an astonishingly wide range of masses. According to their results, the up quark weighs approximately 2 mega electron volts (MeV), which is a unit of energy, the down quark weighs approximately 4.8 MeV, and the strange quark weighs in at about 92 MeV.
What is a quark in simple terms?
A quark is an elementary particle with an electric charge. Quarks are held together by what physicists call “the strong force” or “the strong nuclear force.” The most stable of these quark combinations, or hadrons, are protons and neutrons — the basic building blocks of atoms.
What does the God particle prove?
Particle physics The Higgs boson validates the Standard Model through the mechanism of mass generation. As more precise measurements of its properties are made, more advanced extensions may be suggested or excluded.
What is the charge of a strange quark?
characteristics. Strange quarks (charge −1/3e) occur as components of K mesons and various other extremely short-lived subatomic particles that were first observed in cosmic rays but that play no part in ordinary matter.
What does each quark do?
The Atom Builder Guide to Elementary Particles Quarks make up protons and neutrons, which, in turn, make up an atom’s nucleus. Each proton and each neutron contains three quarks. A quark is a fast-moving point of energy. There are several varieties of quarks.
Is a photon a quark?
Quarks in most cases we study, are particles. There is distinction between certain types of particles. Thus a particle like a quark is more like a proton, somewhat like an electron, but very different than a photon. For one, the first two have a mass, the photon does not.
What does a charm quark do?
Explain it in 60 seconds. The charm quark is one of six quarks that, along with leptons, form the basic building blocks of ordinary matter. It is hundreds of times more massive than the up and down quarks that make up protons and neutrons.
What does a strange quark do?
Like all quarks, the strange quark is an elementary fermion with spin 12, and experiences all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions. …
