Section Learning Objectives. By the end of this section, you will be able to do the following: Explain wave behavior of light, including diffraction and interference, including the role of constructive and destructive interference in Young’s single-slit and double-slit experiments.
This principle works for all wave types, not just light waves. The principle is helpful in describing reflection, refraction and interference. shows visually how Huygens’s Principle can be used to explain reflection, and shows how it can be applied to refraction.
Diffraction is the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave.
Diffraction is the bending or spreading of light through an opening or around an obstacle. Goethe "flexibility of light" Why is it possible to hear around corners, but not see around them? Diffraction of laser light through a vertical opening of decreasing width.
Diffraction can send a wave around the edges of an opening or other obstacle. A single slit produces an interference pattern characterized by a broad central maximum with narrower and dimmer maxima …
In this chapter, we show how the phenomena of interference and diffraction arise from the physics of the forced oscillation problem and the mathematics of Fourier transformation. We begin by discussing interference from a double slit. This is the classic example of interference.
Summary. Diffraction … is the bending or spreading of a wave around an obstacle or through an opening. is most apparent when the size of the obstacle or opening ( a) and the wavelength of the wave ( λ) are of the same order ( a ~ λ ). A shadow is a region behind an obstacle into which a wave does not easily diffract.
