3-1. What’s the microwave? (2/2)

3. The safety of microwave oven

Since the microwave oven can’t make the native fire like gas, you have no use for worrying about the fire. Because it doesn’t become hot like the ordinary electric range. It has been used in the dinner car of the trains etc.

Microwave oven has the shielded structure strictly with metal case not to leak electric wave at once not only using but on opening the door.

Because it uses the electric wave, the x-ray is never emitted. The UHF wave generally called microwave is like the electric wave of the TV or the radio and is used for the wireless communication, the radar and the UHF medical instruments (using 2450 MHz like that of the microwave oven, etc).

4. Definition of electric wave

*An electric wave is the electron wave of the frequency from 10 KHz to 3,000,000 MHz.

*Wave length of 2450 MHZ.

λ	c	300000 Km
	f	0.122 m 12.2 cm
		245000 KHz

λ: Wave Length Where c: The Velocity of Light

f: Frequency

The division from the sound frequency to the light frequency.
