Light energy is produced by the activity of what around the what of an atom?
light may be produced from an object by simple heating. This glow is not characteristic of any particular element. When a chemical element is heated to a great degree, then the electrons will be forced into higher orbits than those which they usually occupy. When the chemical element cools, the electrons will emit the energy they absorbed, and will emit a light which is quite specific to the particular element. This is the method by which we can determine which chemical elements are in a distant star. Incidentally, the timeline of the Big Bang suggests that the universe remained dark until the matter cooled enough to condense into atoms then eventually, the first stars. This may have been as late as 150 million years to 1 billion years after the Big Bang. In those early years the only radiation may have been the 21cm hydrogen line.
What is the difference between chlorophyll and photosynthesis?
Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. The Calvin cycle is the set of chemical reactions that take place in chloroplasts during photosynthesis. The cycle is light-independent because it takes place after the energy has been captured from sunlight.
When is light absorbed?
Light is absorbed by the chloroplasts in chlorophyll in the first step of photosynthesis, which makes energy from the sun. Absorption of light is the first step in photosynthesis to do photolysis of water
How is chemical energy produced?
The chemical reaction that creates energy from the digested food, after the food has been absorbed into the body, is called the Kreb's Cycle. It is a series of chemical reactions that converts carbohydrates, proteins, fats, and alcohol into the very basic energy molecule called ATP.
What is light converted into during photosynthesis?
Light doesn't become energy, energy becomes light. When electrons in atoms absorb energy from electricity in our light bulbs or nuclear fusion in the sun, or even during some chemical reactions, like fire, they jump to higher energy levels. Thing is though, they don't stay there. WHen they jump back to their original energy level, they will release a photon of electromagnetic radiation. (sometimes light) Now, that light can be converted into different forms of energy. Mostly heat like when the Earth absorbes light from the Sun and stores it in the oceans as heat. Also it can be converted into electricity when photons of light bump electrons in photovoltaic material out of their orbitals and make them flow through a wire. That is what electricity is, a flow of electrons in a wire. If your question is really how does light become electricity, GOOGLE photovoltaic cells and that will explain it more clearly. By the way, the effect you read about is what Albert Einstein won a Nobel Prize for and it has helped defined the dual nature of light ever since. There is one other way light becomes energy. Plabts store the energy from the Sun in molecules of starches and sugars made of water (H2O) and carbon dioxide (CO2) using sunlight to reaarange the atoms in a chemical reaction. These starches and sugars can then be eaten by other organisms, mainly animals, to give them the energy they need to live. GOOGLE Photosynthesis and Respiration to see how this all works. REMEMBER THIS!!!!! Law of conservation of energy tells us that energy cannot be created or destroyed. All the energy in the universe has always been here and will always be here as long as the universe exists. Thing about energy is that it can be converted into different forms, like light into heat, but it can't be created or destroyed; only converted.
How much of Ontario's energy is produced using non renewable energy sources express your thoughts on this?
29% of Ontario's energy is produced using non renewable energy sources. If that number is valid that would be one of the greenest energy areas in the world. Hydroelectric is certainly available there and the ability to use it has apparently been well used. Awesome job Ontario!
How long has solar energy been utilized?
Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies.
What causes exhaustion?
A buildup of fatigue poisons (toxins produced during exercise or work) in the body, and the using-up of food energy, without rest or the replacement of what has been used.
How do you make project on conservation of energy?
You could select a basic scenario to show, using Sankey diagrams that no energy has been lost. For example you could use the simple example of a bulb tuning electrical energy into useful light energy and wasted heat energy.
What does the energy of a light bulb change into after the lamp has been lit for a while how can you measure the change?
The energy of a light bulb primarily changes into heat and light when lit for a while. This transformation can be measured using a thermometer to track the increase in temperature around the bulb, and a lux meter to measure the amount of light emitted.
Is the sun the origin of nuclear?
The sun obtains its energy from the fusion of hydrogen isotopes. Nuclear energy on earth works by using the energy released when uranium fissions. Uranium was not formed by the sun, it must have been produced by some earlier stellar event, perhaps a supernova, which we do not as yet understand.
What lets you know energy has been released?
The electrons are excited and they emit light. So light.
What are 3 forms of energy that light can be transformed or converted into when it has been absorbed by a surface?
Light energy can be transformed into thermal energy (heat), chemical energy (in photosynthesis), and electrical energy (in photovoltaic cells) when absorbed by a surface.
What does the energy a light bulb change into after the lamp has been lit for a while?
The energy from a lit light bulb is mainly transformed into heat and light. The electrical energy from the power source is converted to light energy and a smaller amount of heat energy, which is emitted as infrared radiation.
What are two uses for water that has been heated by rock?
energy produced by the heat within the earth

What are some forms of energy that is on Earth that is transformed from sunlight energy?
Wind energy, water energy, energy from burning wood, even petroleum, since it is believed this has been produced by decomposition of plants.
