Why does humans perceive a red dress as the color red?

A- The molecules of the dress do not absorb red light wavelengths

B- The molecules of the dress absorb green and blue light wave lengths

C- A red dress will primarily absorb red light wave length

D A red dress will not absorb light wave length from non-red colors

I think -C

if the dress absorbed red light, then red would not be reflected to your eyes ... the dress would not look red

Great job! The correct answer is C - A red dress will primarily absorb red light wavelengths.

To understand why humans perceive a red dress as the color red, we need to consider the properties of light and how it interacts with objects.

Visible light is made up of different wavelengths, each corresponding to a different color. When light hits an object, some wavelengths get absorbed by the object and others get reflected. The wavelengths that are reflected back reach our eyes, allowing us to see the color of the object.

In the case of a red dress, it appears red because the molecules of the dress primarily absorb light wavelengths from non-red colors (like green and blue), while reflecting back or transmitting the red light wavelengths. This means that when white light (which contains all the colors of the spectrum) falls on a red dress, the dress absorbs most of the light except for the red part, which gets reflected back and reaches our eyes. Our eyes perceive this reflected light as the color red, resulting in us seeing the dress as red.

So, in summary, a red dress primarily absorbs non-red light wavelengths and reflects or transmits the red light wavelengths, which leads to our perception of it as the color red.
