![]() ![]() ![]() Since light’s wavelength is very small compared with the size of the door, it acts like a ray. (a) Light passing through a doorway makes a sharp outline on the floor. Each point on the wavefront emits a semicircular wave that moves at the propagation speed \boldsymbol, about three times smaller than the width of the doorway). A wavefront is the long edge that moves, for example, the crest or the trough. ![]() The new wavefront is a line tangent to all of the wavelets.įigure 2 shows how Huygens’s principle is applied. Starting from some known position, Huygens’s principle states that:Įvery point on a wavefront is a source of wavelets that spread out in the forward direction at the same speed as the wave itself. The Dutch scientist Christiaan Huygens (1629–1695) developed a useful technique for determining in detail how and where waves propagate. ![]() The direction of propagation is perpendicular to the wavefronts (or wave crests) and is represented by an arrow like a ray. A transverse wave, such as an electromagnetic wave like light, as viewed from above and from the side. The view from above is perhaps the most useful in developing concepts about wave optics. The side view would be a graph of the electric or magnetic field. From above, we view the wavefronts (or wave crests) as we would by looking down on the ocean waves. A light wave can be imagined to propagate like this, although we do not actually see it wiggling through space. Discuss the propagation of transverse waves.įigure 1 shows how a transverse wave looks as viewed from above and from the side.Get the free view of Chapter 7, Wave Optics Physics 12th Standard HSC Maharashtra State Board additional questions for Mathematics Physics 12th Standard HSC Maharashtra State Board Maharashtra State Board,Īnd you can use to keep it handy for your exam preparation.
