MICROWAVES

WHAT IS A MICROWAVE?

• Microwaves are something that can be used for
• transmitting things, like a radar, and more.
• It has wavelengths that are measured in centimeters
• It has a higher frequency than radio waves, but
• Lower frequencies than infrared waves.

WHERE ARE THEY?

• Microwaves are the second wave in the
• Em spectrum.
• Shorter wavelengths, higher frequencies, and
• Higher energy than any other radiowaves.

ARE MICROWAVES HARMFUL?

• MICROWAVES CAUSE NO HARM TO PEOPLE
• It doesn't matter how far away a person is from a microwave oven since it cannot harm people
• Microwave ovens can be dangerous un-microwavable items are used.
• Federal standard limits the amount of microwaves that can leak from an oven throughtout its lifetime
• to five milliwatts of of microwavr radiation per square centimeter at approximately two inches

HOW DO MICROWAVES HEAT FOOD?

• They use them by vibrating the water at an
• Atomic level and generate heat.
• Or making the water and fat molecules rotate
• Making it heat up.

FACTS

• Microwaves were first used in WW2
• Help disinfect hospital waste
• In some causes microwaves relieve symptoms
• Better than drugs.
