A Moment of Science
Have you heard the phrase, "Let's nuke it in the microwave!" Well, Nuclear power and microwaves really don't have much in common.
MTV for Martians? Maybe not, but the idea of broadcasting into space is not as far out as you'd think!
If E.T. does try to phone us how will we know it? Find out on this Moment of Science.
The secret is in the unique way microwaves work. Conventional ovens heat up the air inside the oven first then heat up the surface of the food and then heat up the inside. Microwave ovens cook the inside of the food right away, without heating up the surrounding air. They do this by using high frequency electromagnetic waves.
Microwaves are low energy electromagnetic waves that have so little energy they can’t trigger chemical reactions in the molecules they encounter.
