Diffraction is the slight bending of light as it passes around the edge of an object. Newton believed that refraction could be explained by his laws of motion, with particles of light as the objects in motion. This is illustrated by the wave model of light and the particle model of light, which together describe the waveparticle duality in which light is understood to possess both wave and particle functions. Interference is described using real and complex numbers in anticipation of quantum mechanics. We know that visible light is the type of electromagnetic wave to which our eyes respond. Waves have been of interest to philosophers and scientists alike for thousands of years. Shine it at a couple of closelyspaced double slits and project the diffraction pattern onto a distant screen. The quantummechanical theory says that light is both a particle and a wave. Something like a well known visualisation of the famous double split, but instead of the splits just havnig the possibility to have multiple sources with different frequencies. The wavelength of light is the distance from crest to crest of the wave, or from hollow to hollow.
In a vacuum, or other uniform mediums, the light waves are spherical, and these wave surfaces advance or spread out as they travel at the speed of light. In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not. Diffraction of light animation best to understand class 12 physics. Shine within you so that it can shine on someone else. Like all other electromagnetic waves, it obeys the equation c f. Its dual behavior is partly explained by 1doubleslit experiment of thomas young who represents the photons motion as a wave and also by 2the photoelectric effect in which the photon is considered as a particle. Optics is the physical science that studies the origin and propagation of light, how it changes, what effects it produces, and other phenomena associated with it. These video tutorials along with short notes will teach you the basics of wave theory of light or wave optics, huygens principle and wave theories of reflection, refraction, superposition and interference, diffraction, and polarization etc for cbse, iitjee, medical entrance and various state board exams preparation.
This was contrary to common opinion at the time, which was widely biased toward the theory that light is a stream of particles. Huygens put forward his wave theory according to which light energy propagated in the form of wave, with the help of wave theory he could successfully explain the phenomenon of reflection and refraction, interference and diffraction all. Although there was a wave theory of light that was contemporary with newtons, put forth by christiaan huygens, it couldnt explain the. The animation finishes by adding visual clues to the interfering wave fronts for both constructive and destructive interference. The rectilinear propagation of light is explained by the advancement of wavefront along the direction of normals drawn to it.
If artist name appears next to the animation or on the animation then you must check the.

Workflow enhancements and powerful new tools solve your animation and design challenges and streamline your creative process.
What is the basic explanation for wave theory of light. On the other hand, the particle theory of light suggests that light is transmitted in packets of energy called photons, each of energy ehf, where f is the frequency and h. Another supporter of the wave theory was leonhard euler. This module introduces the history of wave theory and offers basic explanations of longitudinal and transverse waves.

The wave theory of light views light as two transverse waves, one made of an oscillating magnetic field and the other an oscillating electrical field. We have been increasingly using flash animations for illustrating physics content.

Light, like water waves, reflects from surfaces, spreads when passing through small holes, and carries energy in a transverse field.
