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; Perform calculations involving diffraction and interference, in particular the wavelength of light using data from a two-slit interference pattern
According to the superposition principle, the net displacement is simply given by the vector or the algebraic sum of the individual displacements. Interference is the combination of two or more waves to form a composite wave, based on such principle. The idea of the superposition principle is illustrated in Figure 14.1.1. (d) .
Experiment 9: Interference and Diffraction. OBJECTIVES. 1. To explore the diffraction of light through a variety of apertures. 2. To learn how interference can be used to measure small distances very accurately. By example we will measure the wavelength of the laser, the spacing between tracks on a CD and the thickness of human hair. WARNING!
Describe the combined effect of interference and diffraction with two slits, each with finite width; Determine the relative intensities of interference fringes within a diffraction pattern; Identify missing orders, if any
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.
Explain behaviors of waves, including reflection, refraction, diffraction, interference, and coherence, and describe applications based on these behaviors; Perform calculations related to applications based on wave properties of light
With real slits with finite widths, the effects of interference and diffraction operate simultaneously to form a complicated intensity pattern. Relative intensities of interference fringes within a diffraction pattern can be determined.
