Co je mikrovlnn\u00e1 trouba?
Mikrovlnn\u00e1 trouba neboli mikrovlnka je kuchy\u0148sk\u00fd spot\u0159ebi\u010d, kter\u00fd m\u011bn\u00ed elektrickou energii na druh elektromagnetick\u00fdch vln, kter\u00fdm se \u0159\u00edk\u00e1 mikrovlny.<\/p>\n\n\n\n

Je to podobn\u00e9 jako kdy\u017e m\u00e1te studen\u00e9 ruce a sna\u017e\u00edte se je zah\u0159\u00e1t tak, \u017ee je o sebe za\u010dnete t\u0159\u00edt. U mikrovlnn\u00e9 trouby se ale teplo uvol\u0148uje na molekul\u00e1rn\u00ed \u00farovni.
