When we look at a red apple, we perceive its color through a combination of transmission, reflection, and absorption of light. The surface of the apple reflects light that is red in color, while also absorbing other wavelengths of light. The red light that is reflected towards our eyes is what we see, giving the apple its characteristic red color. This process of light interacting with the object's surface and being transmitted, reflected, and absorbed allows us to see an object's color.
