呢個廣告真騙人, remember high school physics
微波(wave)能...每一秒作出500百萬頻率(Hz)振動
That means 500 MHz. That's not 微波, just UHF 超高頻, 800MHz以上才是微波,
Yes, 微波 can 以振動將能量轉化為高熱在皮膚起作, that's how the cooking microwave oven works.
So their treatment is similar to standing close to an operating microwave oven. Haha.作者: Nam 時間: 2010-5-7 12:33
