What energy trasnformations occur in a incandescent light bulb?
In an incandescent light bulb, electrical energy is transformed into thermal energy and then into light energy. When electricity flows through the filament of the bulb, it heats up and becomes white-hot, producing thermal energy. This thermal energy then causes the filament to glow and emit light energy.
Does an incandescent bulb and a light stick use the same form of energy to create light?
No. The incandescent bulb uses electrical energy and the light stick uses chemical energy.
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
Fluorescent light more energy efficient than incandescent light?
Yes.
What device converts electrical energy into heat and light energy?
An incandescent light bulb would be a prime example.
What form of energy an incandescent light bulb is converted into when approximately 98 percent of electricity is used?
The 98 percent would be light energy, or electromagnetic radiation, and the other 2 percent would be converted into thermal energy, or heat.

Which type energy other than light energy is produced by incandescent light?
heat energy
What type of energy other than light energy is produces by incandescent light?
heat energyheat energy
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
What type of energy besides light energy is produced by incandescent lights?
Heat.
How do we generate thermal energy?
Thermal energy is simply heat. Light a fire.
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.
Fluorescent light more energy efficient than incandescent light?
Yes.
How does light energy transfer?
thermal energy
Give you two sources of light energy?
Two sources of light energy include the sun and incandescent light bulbs.
