Chapter 1 The Nature of Light: Wave-Particle Duality Reflection of Light The earliest accounts of light reflection originate from the ancient Greek mathematician Euclid, who conducted a series of experiments around 300 BC revealing how light is reflected. However, it was only a millennium and a half later that the Arab scientist Alhazen proposed a law describing what happens to a light ray when it strikes a smooth surface and then bounces off into The reflection of Mount Hood in space. Trillium Lake Angle of incidence equals the angle of reflection on a mirror Basic Physical Optics. Part 1 Corpuscle Theory of Light The ancient Greece scientist Pythagoras (VI – V B.C.) postulated that every visible object emits a steady stream of particles that stimulated the sense of sight when entering the eye. Aristotle (IV B.C.) however stated that light travels in a manner similar to waves in the ocean. Isaac Newton Supported by the immense scientific authority of Sir Isaac Newton (1642 - (1642 - 1727) 1727), the corpuscle theory of light dominated until the beginning of the 19th century. It appeared to be easy enough to picture light as a stream of particles when explaining reflection (Isaac Newton, Opticks, 1704). With much more difficulty, the corpuscle theory modeled refraction and dispersion of light. However, it is not at all surprising that the corpuscle theory of light attracted physicists for centuries. It will be experiencing rebirth in the 20th century as the theory of photons, explaining many properties of light, in particular the photoelectric effect (see later in this Chapter).

Basic Physical Optics. Module 1 Spectrum of Visible EM Radiation I. Newton divided the visible spectrum, to the human eye, into seven colors: red, orange, yellow, green, blue, indigo, and violet (this order being popularly memorized by using the mnemonic ROY G. BIV); indigo is often not recognized as a separate color ). violet 380–450 nm blue 450–495 nm green 495–570 nm yellow 570–590 nm orange 590–620 nm red 620–750 nm EM radiation of one particular wavelength (or narrow range of wavelengths) has one single color. It is referred to as monochromatic. Waves of just one wavelength (or frequency) are conventionally termed monochromatic in all ranges, not necessarily in the visible. Basic Physical Optics.
