    • 2.1: Introduction
      This page explains the visible light spectrum as classified by Sir Isaac Newton, detailing the wavelengths perceptible to humans and distinguishing between visible and non-visible electromagnetic radiation. It describes how wavelength correlates with color, with violet having the shortest wavelengths and highest energy, and red the longest and lowest.
    • 2.2: The Physics of Light and Colour
      This page explains the principles of light as electromagnetic radiation, its wave-particle duality, and the visible spectrum. It covers the historical development of optics and its applications, including artistic devices like the Camera Lucida and the principles behind 3D vision techniques. Additionally, it discusses lasers, optical fibers, and photovoltaic cells, highlighting their technological significance.
    • 2.3: Colour in Chemistry
      This page covers key techniques for measuring color, including spectrophotometry and colorimetry, highlighting their significance in industries like chemistry and design. It details types of luminescence, including chemiluminescence and electroluminescence, and discusses color changes in ectotherms. The processes of black and white and color photography are examined, along with chromatography's role in separation.
    • 2.4: The Eye- How We See Colour
      This page delves into the intricate mechanisms of human and animal vision, comparing the eye to a camera where light is transformed into signals for the brain. It covers human color perception, including challenges faced by color-blind individuals and the phenomenon of synesthesia. The text also discusses animal vision, highlighting how different species perceive colors and the evolutionary adaptations therein.
