MICROWAVES

WAVELENGTH
- Microwaves are a form of electromagnetic radiation with a wavelength ranging from 1m to 1mm with frequencies of between 300Mhz(100 cm) and 300GHz(0.1cm)
- The way these waves are created is from many different types of transmitters, such as cell phones and microwaves.
Comparisons
- Since microwaves are so small, scientists have often compared them to be as small as a bee, or maybe even a period.
HARMFUL?
- Microwaves can be good but yet bad at the same time.
- Studies have shown that microwaves can be safer than surgery. For example a microwave can heat an enlarged prostate, causing the extra tissue to disappear.
- The negative side is it gives off a bad radiation, such as prolonged exposure to significant levels of microwaves which can cause cataracts making it hard to see clearly.
APPLICATIONS
- The way we use microwaves is through cell phone towers, we use them to give information from one place to another.
- Also we use microwaves to heat up foods, since it gives off radiation it causes the water to heat up.

INTERESTING
- In the industry, they help decrease air pollution, disinfect hospital waste, and clean up contaminated soil.
- It's possible to transfer data using microwaves.
- Scientists discovered there is a low level of microwave under normal conditions, they say it's because microwaves can enter the Earths atmosphere easily.
