SUMMARY

The discussion clarifies that the human eye cannot detect audible frequencies, which range from 20 Hz to 20,000 Hz. It emphasizes that light and sound waves are fundamentally different; light consists of electromagnetic waves, while sound comprises mechanical vibrations in a medium like air. The eye detects wavelengths from 400 to 700 nm, corresponding to frequencies between 4.3 x 1014 Hz and 7.5 x 1014 Hz, far exceeding the audible range. Therefore, the notion of seeing audible frequencies is scientifically unfounded.

PREREQUISITES
  • Understanding of sound wave properties and frequencies
  • Knowledge of electromagnetic spectrum and light wavelengths
  • Basic principles of human sensory perception
  • Familiarity with the differences between mechanical and electromagnetic waves
NEXT STEPS
  • Research the electromagnetic spectrum and its various ranges
  • Study the properties of sound waves and their behavior in different mediums
  • Explore the mechanisms of human sensory perception, focusing on the ear and eye
  • Investigate the science behind wave interactions and their implications in physics
USEFUL FOR

This discussion is beneficial for students of physics, audiologists, and anyone interested in the principles of sound and light, as well as their interaction with human perception.

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.
 
Physics news on Phys.org
The eye detects light (electromagnetic waves) with wavelengths approximately from 400 to 700 nm. This corresponds to frequencies from [itex]4.3 \times 10^{14}[/itex] to [itex]7.5 \times 10^{14}[/itex] Hz. This is very very very far from the audible range.

Besides, light waves (waves of electric and magnetic fields) and sound waves (waves of spatial vibrations of air molecules) are completely different in their fundamental nature. Even if you had electromagnetic waves in the range of 20-20000 Hz (which wouldn't be light, but very low frequency radio waves), you wouldn't be able to hear them.
 
the medium that supports sound and light are different. Light consists of electrical vibrations, while sounds are mechanical: it is air, or a material that vibrates. our brain is made to transform mechanical impulses of the ear and electrical impulses of the eye
