Question

1. explain why one car might appear blue to your eye while another one appears red

Explanation:

The color we perceive is due to the wavelengths of light that an object reflects. A blue - colored car reflects light in the blue - wavelength range (around 450 - 495 nm) and absorbs other wavelengths. Similarly, a red - colored car reflects light in the red - wavelength range (around 620 - 750 nm) and absorbs other wavelengths. Our eyes have photoreceptor cells called cones that are sensitive to different wavelengths of light, and when light of a certain wavelength range hits these cones, we perceive a corresponding color.

Answer:

The color perception is based on the wavelengths of light that the cars reflect and the sensitivity of our eye's cones to those wavelengths.
