![]() ![]() Starting from some known position, Huygens’s principle states that every point on a wave front is a source of wavelets that spread out in the forward direction at the same speed as the wave itself. The following two videos cover the wide range of wave behaviour, including reflection, refraction, diffraction and wave superposition. The Dutch scientist Christiaan Huygens (16291695) developed a useful technique for determining in detail how and where waves propagate. Wave superposition occurs when two or more waves are travelling through the same medium at the same time, the net displacement at any point in time, is simply the sum of the individual wave displacements. The same law of reflection is followed for both sound and light, so that focusing a sound wave is equivalent to focusing a light ray. Put up a barrier to explore single-slit diffraction and double-slit interference. Reflection is the phenomenon wherein a beam of light incident on an object bounces off, i.e., reflects of its surface. Diffraction is the bending of waves around obstacles and openings. Make waves with a dripping faucet, audio speaker, or laser Add a second source to create an interference pattern. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated, while refraction is the change in direction of a wave passing from one medium to another. In this post, we explain the behaviour of waves in a variety of situations by investigating the phenomena of reflection, refraction, diffraction and wave superposition, as a part of the Prelim Physics course under the module Waves and Thermodynamics and sub-part Wave Behaviour. Reflection and refraction are common properties of light and sound. What is reflection, refraction, diffraction and wave superposition?
