有没有动物能看到Wi-Fi或蓝牙信号?

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和蓝牙是波长为6厘米至12.5厘米的无线电信号。这是人类可见光波长的10万倍。许多动物，包括吸血蝙蝠和某些鱼类和蛇类，都能感知红外辐射，但这种辐射的波长只有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.

较长的波长所携带的能量要少得多，如果没有某种谐振器来放大信号，就无法被探测到。2009年，法国病毒学家Luc Montagnier声称细菌DNA可以发射无线电波，但他的研究结果遭到了科学界的广泛批评，也没有被复制保存下来。所以到目前为止，我们还不知道有哪种生物能探测到无线电频率信号或与之通信。
