options:

visible waves
visible waves

X-ray waves
X-ray waves

infrared waves
infrared waves

radio waves

1 answer

The most appropriate option for a device that allows humans to communicate through detectable light would be visible waves. Visible light is detectable by the human eye and can be used effectively for communication purposes, such as in applications like fiber optics or visual signals.

While infrared waves can also be used for communication (e.g., remote controls), they are not visible to the human eye. X-ray waves and radio waves do not fit the criteria of "detectable light" in the same manner as visible waves do. Therefore, the correct answer is:

visible waves.
