If you don't think light bulbs, at least the incandescent kind, can heat much, I'd like to invite you to visit my stage, where I can put several tens of thousands of watts on you and we'll see about "can't heat much." Bring a towel.
That aside... it has to do with the black body/cavity radiation curve. A radiator doesn't emit visible light because it's not hot enough; you need to reach about 900 degrees Fahrenheit to get much of anything in the visible light region. The filament in an incandescent bulb gets up to around 2700 K (almost 4500 degrees Fahrenheit).
What else can I help you with?
What forms of an energy does an lamps give out?
The answer is Radiant energy. Infrared light has properties of radiant energy in the form of either a wave or a particle, but not both at the same time, depending on how you look at it.
Why are all CFL lamps more efficient than incandescent lamps?
CFL lamps are more efficient than incandescent lamps because they produce light using a different method - they convert electrical current into ultraviolet light which is then converted into visible light by a phosphor coating inside the lamp. This process is more energy-efficient compared to incandescent lamps, which produce light by heating a filament inside the bulb.
What is the Uses of Radiant Energy?
Radiant energy is used in technologies such as solar panels to convert sunlight into electricity, in infrared heaters for heating purposes, and in ultraviolet lamps for sterilization and fluorescent lighting. It is also utilized in various medical imaging techniques like X-rays and MRI scans for diagnostics and treatments.
Heat lamps in a fast food restaurant keep food warm through the process of?
Heat lamps in a fast food restaurant keep food warm through the process of radiant heat transfer. The lamps emit infrared radiation that warms the surface of the food, helping to maintain its temperature without overcooking it. This method allows for a consistent level of warmth without altering the food's texture or taste.
What are the different types of visible light sources available for everyday use?
The different types of visible light sources available for everyday use include incandescent bulbs, fluorescent tubes, LED lights, and halogen lamps.

What is an example of ultraviolet waves?
Ultraviolet waves are a type of electromagnetic radiation that are invisible to the human eye. An example of ultraviolet waves is sunlight, which contains UV radiation along with visible light and infrared radiation. UV waves are also used in black lights and UV lamps.
What gives off radiant energy on earth?
The Sun is the primary source of radiant energy on Earth, emitting light and heat that we receive through radiation. Other sources of radiant energy on Earth include human-made sources like light bulbs and electronic devices that generate electromagnetic radiation.
What gase use in flurocent lamp?
Fluorescent lamps use a mixture of gases, including mercury vapor and argon, to produce light. When electricity passes through the gases, ultraviolet light is produced, which then interacts with the phosphor coating inside the lamp to create visible light.
Do compact fluorescent lamps contain mercury?
Yes, compact fluorescent lamps (CFLs) contain a small amount of mercury vapor sealed within the glass tubing. This mercury is used to create ultraviolet light when electricity is applied to the lamp, which then generates visible light. It is important to handle and dispose of CFLs properly to prevent environmental contamination.
Is Krypton used in lava lamps?
No, Krypton is not used in lava lamps. Lava lamps typically contain a mixture of wax and a colored liquid, which is heated by an incandescent bulb to create the lava-like movement.
Between fluorescent and incandescent which saves electricity?
Fluorescent lamps deliver more visible light than incandescent lamps using electric power at the same rate. (But incandescent lamps deliver more heat. Just depends on what purpose you're using light bulbs for.)
Is the great wall of china the only visible thing from space?
No, you can see many things. such as street lamps, mount Everest.

Where can you go to find unique floor lamps?
Multiple retailer outlet stores carry different brands and kinds of lamps since many different companies create them. Browse the internet for lamps that catch your eye and consider the cost.

Less then a few present of the energy supplied to 100w lamp appears in the form of visible light What happens to rest of it What could be done to increase this percentage?
The remaining energy is radiated as heat. Making the filament hotter should increase the percentage of visible light. I believe some lamps (like halogen lamps) do this. But the real solution is to use other technologies - like fluorescent lights, or LEDs.The remaining energy is radiated as heat.
