When examining the universe at optical wavelengths you tend to see bright spots (stars/galaxies) with huge expanses of black inbetween. However, at microwave wavelengths you see a background glow, known as the cosmic microwave background. This is a relic from the very early universe and can tell scientists a considerable amount about the early structure of the universe.

What is different macrowave and solardom?
SolarDOM Microwaves are premium microwaves manufactured by the LG company. Some of the different microwaves include: 32Liter SolarDOM, SolarDOM LightOven, and SolarDOM LightOven with grill.
Why is it easier to divert microwaves around an object then to divert light waves?
actually microwaves are easier to bend than light waves because microwaves are larger than light waves
Are microwaves made out of rocks?

What type of rays do microwaves use for cooking food?
Microwaves use electromagnetic radiation, specifically microwaves, to cook food.
How do microwaves give off radiation?
Microwaves emit electromagnetic radiation in the form of microwaves when they are turned on. This radiation is absorbed by food and causes water molecules in the food to vibrate, generating heat that cooks the food.
Are microwaves helpful?
Yes, microwaves are a type of radio that has many uses: microwaves were first used by the Allies in World War 2 in RADAR systems that helped intercept many Nazi and Japanese aircraft (including V-1 "cruise missiles")microwaves were used in telephone company long distance calls from the late 1940s into the 1990smicrowaves are used in WiFi and Bluetooth interfaces on computersmicrowaves are used by cellphones to connect to cell towersmicrowaves are used for cooking purposes by heating the water in the food, making steammicrowaves from stars and other objects are used in radio astronomy to study the universe and see things that ordinary light based telescopes cannotetc.
What impact does microwaves have on humans now?
Overexposure to microwaves can lead to cancer.
