What energy changes are involved when an electric light shines?
When an electric light shines, electrical energy is converted into light energy and heat energy. The electrical energy is converted into light energy, which is the main purpose of the light bulb, while some of the energy is also released as heat energy due to the resistance in the light bulb filament.
What is the main purpose of the light -dependent reactions?
To take in the energy from the sunlight to make glucose to store when there is not sunight. ( at night)
What is the main role played by chlorophyll?
Chlorophyll is the "stuff" that makes leaves green. It's main purpose is to convert the sun's light energy into a more usable form of chemical energy.
What was the purpose of the electric light bulb?
To convert electric energy into light energy
Is lamplight the same as sunlight?
Kinda. The sun's energy is called solar energy. Pretty much the same as light energy, but solar energy's MAIN purpose is also to heat.
What is the main source of light and energy?
The main source of light is the sun
What two forms of energy does a lightbulb produce?
A lightbulb primarily produces light energy through the emission of photons when electricity passes through the filament. It also produces a small amount of heat energy due to resistance in the filament that causes it to get hot.
What is the main source of heat and light ENERGY?
The main source of light is the sun
What is the primary purpose of the light-dependent portion of the energy synthesis pathway in plants?
The primary purpose of the light dependent portion of photosynthesis is to convert light energy into chemical energy stored in ATP and NADPH, which will then be used in the light independent reactions.
What the main purpose of respiration?
Provide energy for food
Does radiant energy serve a useful purpose?
The heat and light we receive from the sun is radiant energy, as is the light we obtain from light bulbs.
What is the main purpose of a laser?
The main purpose of a laser is to focus electromagnetic radiation (light) on to a single point.
