Sure; there are solar ovens that do precisely that.One design is to simply cover an enclosed area with glass. The heat gets "trapped" inside (the glass is transparent for visible light, but not to infrared radiation); and the temperature inside gets hot enough to do baking.
Another design is to concentrate light with a parabolic mirror - concentrating it on a spot where the pot is suspended.
Well, light has to be concentrated to be hot enough to cook food, kinda like using a magnifying glass to burn stuff, even though normal sunlight can't do it alone.A2. And don't forget that microwave ovens typically have a power of about 1kW. A 1kW infrared lamp will heat up food pretty fast.BUT the microwaves penetrate the food to the centre, where they vibrate the water molecule. Whereas you'd have to wait for an IR lamp's heat to be conducted to the centre which will take some time by conduction.Microwaves are a lot more penetrating than visable light. It gets absorbed easier, wheras light reflects, etc.
The frequency range of visible light.
No, x-rays are not visible light.
Well, seeing as it seperates visible light, it follows that it only seperates that visible light into the visible spectrum. You can't make radiowaves or UV rays out of visible light.
EM rays which are in the range of visible light.
You can light up a stove and cook some food. If you are ever stuck alone in the woods that match can provide you with light, warmth, and it can cook food.
Microwaves use radiation to cook food and radiation is a form of light. They do not use actual light bulbs to cook though.
It's a wavelength of light which is outside the visual spectrum.

Warmth, to cook food, and light
visible light is the only VISIBLE light.
Visible light has a shorter wavelength, and therefore a higher energy content than microwaves. You may wonder how this is possible, when microwaves heat up your food so effectively, and visible light doesn't. That's because a microwave oven produces microwaves that are tuned to the exact resonant frequency of the water molecule. Otherwise, the microwaves would heat your food even less than an ordinary light bulb would. =============================================================================== Your answer is only partially correct. The difference in frequency (visible light is much higher) makes the energy content of visible light 30,000 to 50,000 times greater than that of microwave radiation. Where you are incorrect is saying that the microwaves have "the exact same resonant frequency of the water molecule". Actually, the resonant frequency of water at room temperature is about 22 gigahertz (GHz), while the frequency of the waves in a microwave oven is 2.45 GHz, almost an order of magnitude lower. Further, as the water gets hotter, its resonant frequency increases and so couple the microwave energy less and less; so warm and hot water heat more slowly that cold water. The major reason visible light isn't used to cook food is that its penetration depth into the food (directly related to its wavelength) is so small that it can only heat the surface - it has virtually no penetration into the food. Visible light has been used, in the form of a halogen bulb in some microwave ovens so the microwave heat or cook the bulk of meat, while the visible light browns and even crisps the surface.
yes its does because when the microwave is on and the plate is rotating,the light is actually heating the food. It is not the visible light that does the heating, that is provided simply so you can see inside the oven. It is the microwaves that do the heating, by agitating molecules of water in the food. That's why you can't heat dry food in microwave oven. The microwaves are EM radiation like visible light, but a different wavelength.
light a small fire and put a pot over it. then put soups and other foods into it. It would cook and there you have it, nice hot food!!
The answer is visible light. Visible light is light that can be seen with a naked eye
Visible light is visible (for the human eye), infrared is not. Infrared has a longer wavelength, and a higher frequency. visible light is visible to human i.e the VIBGYOR, above vibgyor are ultravoilet light which is not visible to human eye and below vibgyor are infrared light which is also not visible to human eye.
It absorbs different wavelengths of visible light
