An incandescent light bulb does that, as does a radiant heating element. A light-emitting diode (LED) also generates light from electricity from the excitation of a semiconductor junction. A fluorescent bulb can be used to create light from electricity by stimulating the chemical to fluoresce. Gaseous bulbs can generate light from electricity, such as a neon/argon/halogen bulb with a high-voltage applied to the gas inside.

What energy changes take place when a light switch is turned on?
mechanical to electrical to light energy
Does flashlights use electric chemical or mechanical energy?
They use chemical energy and it converts to electrical energy in the bulb and after becomes electomagnetic energy or radiant energy which is the light.
When the flashlight is turned on what energy changes?
A standard flashlight with an incandecent bulb converts electrical energy into two different types of energy; light energy and heat energy.
A 100 watt light bulb converts electrical energy into electromagnetic energy at a slower rate that a 40 watt light bulb?
The higher the wattage, the more electrical energy is being used. In a light bulb the electrical energy is converted to EM energy which appears in both visible and infrared parts of the spectrum, so the answer is no, it will be at a higher rate for a 100 watt bulb
What plant organelle converts light into sugar?
Chloroplast converts light energy into chemical energy.Process is called photosynthesis.
A device that converts light energy into electrical energy?
A solar cell converts light into electrical energy.
What is the device that converts electrical energy in to light energy?
The light bulb.
Which device converts light energy into electrical energy?
A photo-voltaic solar cell
What device converts electrical energy into heat and light energy?
An incandescent light bulb would be a prime example.
What are the conversions of electrical energy give 5 examples?
-- An LED converts electrical energy to light energy. -- A coffee percolator converts electrical energy to heat energy. -- An old-fashioned light bulb converts electrical energy to light energy and heat energy, both at the same time. -- A loudspeaker or ear-bud converts electrical energy to sound energy. -- An electric motor converts electrical energy to kinetic energy. -- A radio transmitter converts electrical energy to low-frequency electromagnetic energy. -- A battery sitting in its charger converts electrical energy to chemical energy.
Does light bulb converts kinetic energy into electrical energy?
No, it converts electricic energy into electromagnetic energy (heat and light)
I have energy. Who has a device that converts radiant energy into electrical energy?
You could be a Solar electrical panel made up of many solar cells converting our Sun's radiant light energy into electricity.
Which part of the eye converts light into electrical energy?
The retina converts light into nerve impulses, which are NOT electrical in nature.
What is a device that transforms one form of energy to another?
Water heater converts electrical energy into heat energy Fan converts the same into mechanical Speaker converts electrical energy into sound using a magnetic field. A charger changes electrical energy into chemical energy A bulb filament changes electrical energy into light energy
What is meant by solar cell?
A solar cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
What is a part of a solar panel that absorbs light and converts it into electrical energy?
The photocell is the part of a solar panel that absorbs light and converts it into electrical energy.
A dry cell is used in a flashlight to convert what to light?
Chemical energy into light energy more specifically i.e. dry cell converts chemical energy into electrical energy flashlight converts electrical energy into light energy
