.Within the visible spectrum of light, there are many colors: red, orange, yellow, green, blue, indigo, and violet. What characteristic of each of these colors makes this spectrum of light visible to the human eye?

Each color has a different wavelength.

Each color travels through different substances (mediums) .

Each color must travel a different distance to our eyes.

Each of these colors make the spectrum of light visible to the human eye because each color has a different wavelength.

Explanation:

The cones of our eyes are a type of photoreceptor. The cone is the cells in the retina that respond to light. Each different cone is senstive to different wavelengths. In order to see different colors, the light reflected off of objects must have a specific wavelength in order to trigger one of the cone receptors.
