Is it possible? It is said that the human being can hear from a dynamic range of 20 hz to 20,000 hz. Apparently, the human eye is not able to detect audible frequencies. I have a question though... Can we see audible frequencies? Our are eyes capable of catching them? If a drop of water comes into contact with the bottom of a glass and I'm able to hear the drops of water through a pattern (periodic vibration) aren't I capable of seeing audible frequencies? I'm confused, someone help me please.
