What is true about energy and how light transforms into heat such as when a light warms up?

Light can be absorbed, and converted to heat.However, if a light-bulb heats up, it's to a great extent due to other effects - for example in the old-fashioned incandescent light-bulb, the electrical energy gets converted FIRST to heat energy; a small part of that heat energy then gets converted into visible light. In other types of light bulbs, the light bulbs get hot mainly because NOT all of the energy gets converted into visible light; part of it gets converted into heat.

Which of the following is the type of energy light has?
Light is energy. But it also has heat energy, because if it is alight then it warms up. However, this is actually kinetic energy (heat is actually kinetic) because the particles are moving to create heat. This would be wasted energy in a lamp.
What is an electric component that transforms electric energy into heat and light?
That is a light bulb, or any filament such as the one in a radiant electric fire.
How heat is produced in nuclear reactor?
The nuclear fission results in mass loss (called mass defect) that transforms into energy according to the formula: E = mc2 (c is light velocity). This energy manifests itself as heat energy.
What kind of energy source transforms heat energy from the Earth into mechanical and electrical energy?
geothermal
When you turn on a toaster what happens to the electrical energy?
The electrical energy gets transformed into electromagnetic (light) energy and thermal (heat) energy.
Is sunlight mechanical energy?
No, it is electrical and light energy, which transforms into heat energy.
A lamp transforms electrical energy into what?
Mostly heat, but that heat causes a filament to glow, which makes light.
When light from the sun warms the grounds the transfer of heat energy is called?
Radiation
How visible light and infrared energy warms earth?
by absorbing them and convert heat
When light from the sun warms the ground the transfer of heat energy is called?
Radiation
Peter warms his hands by placing them at the side of the candle his hands gets heat mainly by what?
He probably gets heat from light energy that then turns into heat energy.
How do you know a light bulb transforms 100 percent of its electricity into light?
You don't. A light bulb transforms only a fraction of its energy into light, and most of it into heat. For an incandescent bulb about 3% is transformed into light, while for a compact fluorescent (low-energy light) about 15% is transformed into light.
What energy transfers take place in a torch?
The battery chemical energy transforms into electric energy that is demonstrated as light.

How heat energy transforms into chemical energy?
Burning release heat, for example.
What does the sun's energy have to do with the weather?
The heat from the energy warms
