What's the difference between microwave and microwave oven?

Microwaves have wavelengths that can be measured in centimeters!The longer
microwaves,those closer to a foot in length,are the waves which heat our food
in a microwave oven.
Microwaves are good for transmitting information from one place to another
because microwave energy can penetrate haze,light rain and snow,clouds,and
smoke.
Shorter microwaves are used in remote sensing.These microwaves are used for
radar like the doppler radar used in weather forecasts.Microwaves,used for
radar,are just a few inches long.
this information is from the NASA site explaining what are wicrowaves and some of their utility.
Microwave oven,however,is a kitchen appliance.It heats food by hitting food with electromagnetic radiation in the microwave spectrum.(See the diagram above).This cause the polar molecules,usually they are water in food,to spin really fast.This spinning energy converted to heat,called thermal energy.This kind of appliance can heat foods quickly and efficiently if the food object is not too thick.If food is too thick,heating evenly can be a challenge.
Now,you see,microwave and microwave oven are 2 different things.In daily communication,people usually understand you meant microwave oven when you say microwave.
Strictly speaking,microwave = an electromagnetic radiation
microwave oven = a kitchen appliance.
微波可以以厘米为单位测量的波长!较长的的微波,有些接近到英尺的长度,是我们用在微波炉中加热食物的波.
微波是很好的传递信息从一个地方到另一个,因为微波能穿透阴霾,小雨和雪,云,和烟雾.
 使用更短的微波遥感.这些微波用于类似雷达的多普勒天气雷达,用于天气预报.用于雷达,微波炉,只有几英寸长.
这个信息是从美国国家航空航天局网站的解释是什么的 wicrowaves 和微波的一些实用.

然而,微波炉是厨房设备.通过在微波频谱的电磁辐射打击食品,加热食物.（见上图中）.这导致极性分子的,他们通常是食品中的水,旋转真快.此旋转能转换成热力,称为热能.这种家电可以快速,高效地加热食物,如果食物不是太厚.如果食物太厚,加热均匀,可以是一个挑战.

现在,你看,微波和微波炉是2个不同的东西.在日常交流中,人们通常理解当你说微波你的意思是炉微波.

严格地说,微波=电磁辐射

微波炉=厨房的用具.
