Part 5/10:
Furthermore, the host discusses the nature of human vision. Our eyes contain three types of cone receptors—S, M, and L—which react to different wavelengths corresponding roughly to blue, green, and red. When light hits an object, it reflects certain wavelengths; for example, a yellow banana reflects wavelengths in the yellow spectrum, activating both red and green cones, which the brain perceives as yellow. The misconception that the banana is "made of red and green" or that the yellow appearance results from moving colors is addressed — in reality, the color depends on which wavelengths are reflected, not on movement.
