有沒有動物能看到Wi-Fi或藍牙信號?

Wi-Fi and Bluetooth are radio signals with a wavelength of 6cm to 12.5cm. This is about 100,000 times longer than the wavelengths of visible light that humans can see. Many animals, including vampire bats and certain fish and snake species, are able to sense infrared radiation, but this only goes up to wavelengths of 1mm.

Wi-Fi和藍牙是波長為6厘米至12.5厘米的無線電信號。這是人類可見光波長的10萬倍。許多動物，包括吸血蝙蝠和某些魚類和蛇類，都能感知紅外輻射，但這種輻射的波長只有1毫米。

Longer wavelengths carry much less energy and can’t be detected without some kind of resonator to amplify the signal. In 2009, the French virologist Luc Montagnier claimed that bacterial DNA can emit radio waves, but his results were met with widespread criticism from the scientific community, and have not been replicated. So to date, we don’t know of any organisms that can detect or communicate with radio frequency signals.

較長的波長所攜帶的能量要少得多，如果沒有某種諧振器來放大信號，就無法被探測到。2009年，法國病毒學家Luc Montagnier聲稱細菌DNA可以發(fā)射無線電波，但他的研究結果遭到了科學界的廣泛批評，也沒有被復制保存下來。所以到目前為止，我們還不知道有哪種生物能探測到無線電頻率信號或與之通信。
