Waves, particles and measurement 1. Sir Isaac Newton’s corpuscular theory of light in Opticks treated light as a stream of particles. 2. Plato thought of light as coming from the gods. 3. The appearance of waves spreading out after moving through an opening is one example of the phenomenon called diffraction. 4. A practical example of destructive interference is sound cancelling headphones. 5. Light is both a wave and a particle. 6. Quantum physics can best be described as the study of matter on discrete, very small scales. 7. The creation of an interference pattern is indicative of wave propagation. 8. Albert Einstein called light energy packets named ‘photons’ for which he won the Nobel Prize in 1921. 9. The linear distance between two successive peaks on a wave is called a wavelength. 10. Light from the most distant galaxies has been travelling for billions of years before reaching our eyes. 11. Sarah notices that when waves from two different sides of a wave tank meet, the waves seem to vanish; she is observing destructive interference. 12.

Thomas Young’s work compared interference patterns in water waves with light produced by his double-slit experiment. 14. Euclid identified properties of light including moving in straight lines and laws of reflection. 15. When the double slit experiment is performed with a strong coherent source of light such as a laser, we observe evidence that light behaves like a wave — true. 16. When peaks and troughs of two waves line up and add together, this is called constructive interference. 17. A wave can be thought of as a pattern, while a particle is a discrete object or quantity. 18. James Clerk Maxwell discovered that light is a type of electromagnetic wave and can travel through the vacuum of space. 19. In much the same way that Newton is associated with laws of classical mechanics, Maxwell is associated with electromagnetism. 20. The work of Christiaan Huygens on light was not widely regarded at the time because it was the opposite of what Newton had proposed. 21. We see water waves readily in the sea, lakes or puddles. We most commonly sense waves in air by hearing. 22. If light is seen to diffract through an opening, then light behaves like a wave.

Waves, particles, and the measurement of light have been foundational to our understanding of physics. The evolution from Newton's corpuscular theory to the wave-particle duality and the development of quantum physics encapsulates a fascinating journey through scientific discovery. This essay explores these concepts, highlighting the contributions of legendary scientists and the phenomena that have shaped our comprehension of light and its behavior.

Sir Isaac Newton's corpuscular theory postulated that light consists of tiny, discrete particles (corpuscles) that travel in straight lines, explaining phenomena like reflection and refraction. Newton envisioned these particles as possessing mass, which allowed him to frame light's behavior in mechanics-based terms. Although his model couldn't explain phenomena like diffraction and interference, it was instrumental in establishing the particulate perspective of light in the 17th century (Newton, 1704). This view was predominant until the wave theory gained prominence in the 19th century.

Contrasting Newton's particle approach, the wave theory introduced by Christiaan Huygens and later supported by Thomas Young challenged the corpuscular view. Young’s double-slit experiment in 1801 provided compelling evidence for wave interference, showcasing patterns of bright and dark fringes resulting from constructive and destructive interference (Young, 1801). Such phenomena, including diffraction, could not be explained by Newton's corpuscular model but were consistent with wave behavior, indicating that light exhibits wave-like properties under certain conditions.

The wave nature of light was further reinforced through Maxwell’s electromagnetic theory. James Clerk Maxwell in the 1860s demonstrated that light is an electromagnetic wave, capable of propagating through the vacuum of space. Maxwell’s equations unified electricity, magnetism, and optics, revealing that oscillating electric and magnetic fields travel through space at the speed of light (Maxwell, 1865). This discovery revolutionized physics by emphasizing that light is a form of electromagnetic radiation, broadening its understanding beyond particles.

In subsequent developments, the advent of quantum physics introduced the concept of wave-particle duality. Albert Einstein in 1905 proposed that light consists of quantized energy packets called photons, explaining phenomena such as the photoelectric effect for which he received the Nobel Prize in 1921 (Einstein, 1905). Photons exhibit particle-like characteristics, such as discrete energy levels, yet can produce interference patterns akin to waves, demonstrating their dual nature. This duality is central to quantum mechanics, which studies the interaction of matter and light on atomic and subatomic scales.

The dual nature of light manifests vividly in experiments involving diffraction and interference. When coherent light sources like lasers pass through slits or around obstacles, diffraction patterns emerge, indicating wave behavior. These patterns are a hallmark of wave propagation, yet the photons themselves strike a detector one at a time, implying particle-like behavior. The principle of superposition explains how waves add or cancel out, producing regions of constructive or destructive interference. Sarah’s observation of the waves vanishing in her wave tank exemplifies destructive interference, a fundamental concept in wave physics (Feynman et al., 1965).

The significance of understanding wave and particle properties extends beyond optics, influencing fields such as quantum computing, telecommunications, and astrophysics. For instance, the observation of cosmic light traveling billions of years from distant galaxies underscores the vast timescales over which electromagnetic waves propagate, providing insights into the universe's evolution (Peebles, 1993). Whether through the lens of classical or quantum physics, the complex nature of light continues to inspire and challenge scientists today.

In conclusion, the journey from Newton’s corpuscular physics to modern quantum theory reflects humanity’s relentless pursuit of knowledge about nature’s fundamental forces. The experimental evidence for light’s wave-like and particle-like behaviors has been integral to this progress, culminating in our current understanding of wave-particle duality. Recognizing these dual properties allows us to appreciate the nuanced and dynamic behavior of light, which remains at the forefront of scientific research and technological innovation.
