Source of energy heat and light?
Sun
Is heat energy produced with the light energy in a torch?
Yes. The heat and light energy in a torch are separate. From the total energy input to the torch (chemical energy from batteries), Some is useful (the light energy) and some is wasted. (heat/thermal energy) The more efficient an appliance is ,the less energy out of the input energy is wasted. For example, an appliance may be 70% efficient. If it is supplied with 100J (joules) of energy, 70J will be useful and 30J will be wasted. Along with light energy, heat energy is also produced by a torch and is wasted. Heat energy is the most common form of wasted energy in appliances. Other appliances will waste energy in the form of heat, though it may not always be obvious.
What is the main source of light and heat during daytime?
sun
What is the source of energy for light waves?
The source of the light is the source of the energy carried by the light. The heat of a fire, the chemical energy in the tail of a firefly, the kinetic energy of the flint scraping across the stone, the heat of the filament in the light bulb, the electricity that powers the LED or the laser, etc.
What type of energy source is the sun using to make the light it sends us?
heat and light
Is star a light source heat source or both?
both
What is the source of darkness and cold since the sun is the source of heat and light?
We're modestly familiar with the source of heat and light. And we know that heat and light both exist and are real. Cold and darkness do not exist. They merely describe the lack of heat and light, respectively.
What form of energy is stored in a torch?
light and heat
What is the primary source of light and heat?
sun is the primary source of heat and light......
Why will earth become cold if there will be no sun why?
Because the sun is our source of both heat and light. Without it, we could not survive and we would have no heat source left.
What is the source of heat and light for all the plants?
The sun is the source of heat and light for plant-life.
Are atmospheric conditions such as temperature moisture light and wind influenced by the sun?
They all are. The sun is the source of both light & heat.
Can you use a hand torch to melt cheese?
Any heat source can melt cheese.
What is the job of the cells and wires and bulb and switch in a torch?
The job of a bulb is to give off heat and light energy
What is the main source of heat and light ENERGY?
The main source of light is the sun
How does a bulb glow when a torch is switched on?
If your torch has an incandescent bulb in it, the resistance of the wire in the bulb generates enough heat that light is created. If your torch has an LED bulb, the PN junction in the diode creates light when the diode is forward-biased.
What is the source of your heat and light?
the sun?
