Important Topics for Resnick Halliday & Walker Fundamentals of Physics Volume 2 Solutions Chapter 36: Diffraction
The important ideas presented in the Diffraction Chapter of Resnick Halliday & Walker Fundamentals of Physics Volume 2 Solutions is to know how waves suffer from diffraction, demonstrating Fresnel bright spots, and you will know about single slit diffraction. Along with that, you will gain knowledge about the diffraction pattern when the light wavelength is different.
- Single Slit Diffraction: When a passing wave faces an obstacle or any aperture of a size same as that of the wave’s wavelength, these results in waves spread out and because of this it undergoes interference and this interference is called Diffraction.
- The Intensity in Single Slit Diffraction: The intensity of the pattern of diffraction at any given angle is calculated at the centre of the pattern.
- Diffraction by a Circular Aperture: Study the diffraction pattern in a circular aperture like a circular opening or any circular lens through which light can pass. It produces a central maximum and concentric maxima and minima. Rayleigh’s criterion also suggests that when in two objects the central diffraction maximum is at the first minimum of the other, they are on the verge of resolvability.
- Diffraction by Double Slit: When waves cross through a combination of two slits, the result is a mix of double-slit interference as well as diffraction by each of the slits.
- Diffraction Gratings: One of the most important tools in the study of light as well as objects that absorb and emit light is Diffraction Grating. It is a series of slits that are utilized for separating the incident wave to its component wavelength by separation of and display of diffraction maxima.
- Gratings: Dispersion and Resolving Power: The dispersion D of a diffraction grating is an evaluation of the angular separation 2u of the lines it generates for two wavelengths differing by 2l. The resolving power R of a diffraction grating is a calculation of its capacity to make the emission lines of two close wavelengths distinguishable
- X-ray diffraction: When X-ray meets a crystal structure, they suffer from Bragg scattering and it is very easy to see. If X rays are having wavelength I and it is scattering from the crystal planes with separation d, then the angle u, at which there will be maximum scattering is
2d Sin(u) = ml , for m= 1,2,3,…
