As we know that microwaves have less energy than visible light , then do we use microwave oven in cooking food instead of visible light?
Try a different search term... https://en.wikipedia.org/wiki/Easy-Bake_Ovencosmik debris said:Some years ago I saw an advert for a Pizza oven that used light sources for cooking. The ad claimed that they were faster blah blah. I did a quick search but as you can imagine "White light pizza oven" did not return anything useful.
What is the reason?nasu said:x-rays have even more energy per photon. Why do you think they are not used for cooking? I can think of more than one reason.

Why microwaves transfer energy to molecules more efficiently?Grinkle said:I'm pretty sure its because microwaves transfer energy to water molecules very efficiently. If you shine a micro-wave emitting flashlight on some water, it will heat up a lot more than if you shine a visible light emitting flashlight at some water.
Its about the specific frequency of the photons and that matching what water molecules will absorb.
Edit - I did some post-posting Googling (barn door after horse) and I am wrong. Its more about being able to generate enough power at a convenient frequency and how far into the food the radiation can penetrate as its dissipating its energy - not about making water molecules vibrate at some specific frequency.
Electricity can be converted to microwaves with 50-75% efficiency while LEDs have around 15-40% efficiency.Anindya Mondal said:Why microwaves transfer energy to molecules more efficiently?
We use invisible light, such as infrared and microwave radiation, to cook food because these types of light have longer wavelengths that can penetrate deeper into the food. Visible light has shorter wavelengths and would only heat the surface of the food, resulting in uneven cooking.
Yes, visible light can be used to cook food, but only for certain types of food. For example, solar cooking uses the sun's visible light to heat and cook food. However, this method is not as efficient as using invisible light and is limited to sunny days.
No, there are no known health risks associated with cooking food with visible light. However, prolonged exposure to intense visible light, such as from the sun, can cause skin damage and sunburn. This is why it is important to use protective measures, such as sunscreen, when cooking with visible light.
Yes, there are several reasons why infrared and microwave radiation are commonly used for cooking. These types of light are readily available and can be easily manipulated to produce the desired amount of heat. They are also able to penetrate through materials, making them ideal for heating and cooking food.
It is unlikely that visible light could be used to cook food more efficiently than infrared or microwave radiation. As mentioned earlier, visible light has shorter wavelengths and would only heat the surface of the food, resulting in longer cooking times and potentially uneven cooking. Infrared and microwave radiation are better suited for cooking as they can penetrate deeper into the food and heat it more evenly and quickly.
