Precautions while using Microwaves
Microwaves are a form of electromagnetic radiation with wavelengths ranging from as long as one mete
1. What are Microwaves
Microwaves are high frequency radio waves (radiofrequency fields) and, like visible radiation (light), are part of the electromagnetic spectrum. Microwaves are used primarily for TV broadcasting, radar for air and sea navigational aids, and telecommunications including mobile phones. They are also used in industry for processing materials, in medicine for diathermy treatment and in kitchens for cooking food.
2. Use Microwaves for Reheating
We use microwaves for reheating, heating water for tea, sometimes, popcorn, rice, baked potatoes, melting chocolate, softening butter, margarine, or cream cheese, frozen dinners or other things (chicken nuggets or patties), cooking frozen veggies for dinner, and making instant oatmeal for breakfast, this list doesn
3. Electromagnetic radiation spectrum
Microwaves, like visible light, are a part of the electromagnetic radiation spectrum. They are extremely high frequency radio waves. As the frequency of radiation increases, its wavelength decreases, so very high frequencies correspond to very short wavelengths; hence the name microwaves. Infrared radiation, ultraviolet light and X rays are also electromagnetic radiations, but have even shorter wavelengths than microwaves.
4. Metallic materials totally reflect microwaves
Microwaves may either be reflected, transmitted or absorbed by matter in their path. Metallic materials totally reflect microwaves. Most non metallic materials such as glass and plastics are partially transparent to microwaves. Material containing moisture, such as food and even people, absorbs microwave energy. If energy is absorbed at a rate greater than the rate at which the material looses energy (ie. rate of cooling), its temperature will increase.
5. Are Microwave Ovens Safe
When used according to manufacturers instructions, microwave ovens are safe and convenient for heating and cooking a variety of foods. However, several precautions need to be taken, specifically with regards to potential exposure to microwaves, thermal burns and food handling.

Did you Know
No evidence of man's evolutionary ancestors has so far been found in either North or South America. Fossils and other remains suggest that the first Americans crossed the Bering Straits (which at the time was dry land) from Asia between 20,000 and 40,000 years ago.
