Physics Wave Optics Pdf Optics Refraction Wave optics accounts for the fact that light is an electromagnetic wave. as such it can undergo interference and diffraction effects, similar to what can be observed for sound waves. the electric and magnetic field vectors associated with light are perpendicular to the direction of propagation. The changing electric and magnetic fields result in the propagation of electromagnetic waves (or light waves) even in vacuum. in this chapter we will first discuss the original formulation of the huygens principle and derive the laws of reflection and refraction.
Chapter 25 Wave Optics Pdf Diffraction Coherence Physics The principle of superposition states that when two waves overlap in a region, the total disturbance is the sum of the individual disturbances each wave would produce alone. Astronomers call the increase in wavelength due to doppler effect as red shift since a wavelength in the middle of the visible region of the spectrum moves towards the red end of the spectrum. Topics are addressed from a physics perspective and include the propagation of light in matter, reflection and transmission at boundaries, polarization effects, dispersion, coherence, ray optics and imaging, diffraction, and the quantum nature of light. Fresnel was also the first — decades before maxwell’s electromagnetic wave theory of light — to give the correct formulas (given in the notes “light”) for the intensities of the reflected and refracted waves at an interface.

Light is a stream of particles emitted either by the object being viewed or emanating from the eyes of the viewer. newton was the chief architect of the particle theory of light: he believed the particles left the object and stimulated the sense of sight upon entering the eyes. Huygens’s principle works for all types of waves, including water waves, sound waves, and light waves. we will find it useful not only in describing how light waves propagate, but also in explaining the laws of reflection and refraction. For our purposes, in understanding how optical instruments work, the wave theory of light is entirely adequate. we’ll consider the simple case of a sine wave in 1 dimension, as shown in figure 1.3. the distance between successive wave fronts is the wavelength. Introduction : geometrical optics deals with the properties of light like reflection, refraction, dispersion etc on the basis of rectilinear propagation of light (ray of light – light travelling along a straight line).
