Compared with light wave, the wavelength of microwave is much larger. The national standard of microwave is 122mm wavelength (2.45GHZ), while the wavelength of visible light is nanometer. Draw a picture yourself, hehe.

3. The frequency of microwave is close to that of mobile phone (3G), but the signal strength of mobile phone can't be compared with microwave power. The microwave oven will concentrate microwaves to heat food quickly.

4. Preference for microwave materials (water, metal, plastic, ceramics, etc.). ) Go to Baidu to check it yourself.

In addition, infrared light can also heat objects. Halogen lamps in microwave ovens use infrared rays to heat food.

You don't want to buy a microwave oven. If so, I suggest you buy a microwave oven (with a turntable, preferably stainless steel inside).

1. Stainless steel liner is clean and has long service life.

2. Heat evenly with a turntable.

I have bought a microwave oven for 3 years, and the barbecue function has only been used once (light wave is used for barbecue).

I hope I can help you.
