Interference

Home > Physics > Optics (physics) > Interference

Study of the interaction of light waves that produces a net result that is different from the sum of the individual waves.

Wave Properties of Light: Basic understanding of light waves, wave properties (amplitude, wavelength, frequency, phase), and types of waves (transverse and longitudinal).
Superposition Principle: Understanding the principle of superposition where the total disturbance produced by two or more waves is the sum of the disturbances produced by each individual wave.
Huygens-Fresnel Principle: Understanding the principle of wave propagation where every point on a wavefront serves as a source of secondary waves that combine to form the new wavefront.
Coherent and Incoherent Light: Understanding of the concepts of coherent and incoherent light, which determines how light sources interfere with each other.
Diffraction: Understanding of the concept of diffraction, which is the bending of light around the edges of an object or aperture.
Single-Slit Diffraction: Understanding of the diffraction pattern produced by a single-slit aperture, including the intensity and angular distribution of the diffracted waves.
Double-Slit Interference: Understanding of the interference pattern produced by a double-slit aperture, including the conditions for constructive and destructive interference.
Multiple-Slit Interference: Understanding of the interference pattern produced by multiple-slit apertures, including the maximum and minimum intensity positions.
Thin-Film Interference: Understanding of the interference produced by thin films of transparent materials, including the conditions for constructive and destructive interference.
Fabry-Perot Interferometer: Understanding of the Fabry-Perot interferometer, which uses multiple reflections to produce interference fringes in order to measure small changes in wavelength or index of refraction.
Grating Spectroscopy: Understanding of the grating spectroscopy, which uses diffraction gratings to disperse light into its constituent wavelengths to measure spectral lines.
Michelson Interferometer: Understanding of the Michelson interferometer, which uses a beam splitter and mirrors to produce interference fringes to measure small changes in distance or speed.
Interferometry in Astronomy: Understanding of how interferometry is used in astronomy to improve image resolution and measure the properties of astronomical objects.
Polarization Interference: Understanding of the interference produced by polarized light, including the conditions for polarization and the use of polarizers in optical systems.
Nonlinear Optics: Understanding of the nonlinear optical effects, which occur at high intensities, including second harmonic generation, sum frequency generation, and optical parametric amplification.
Young's double-slit interference: This occurs when light waves pass through two parallel slits, resulting in an interference pattern on a screen behind the slits.
Michelson interferometry: This involves splitting a beam of light and reflecting the two beams off of mirrors before recombining them. The resulting interference pattern can be used for precise measurements of distance or refractive index.
Fabry-Perot interferometry: This involves reflecting light back and forth between two parallel mirrors, creating a resonant cavity. The interference pattern that results can be used to analyze the spectral properties of the light.
Thin-film interference: This occurs when light waves reflect off of the front and back surfaces of a thin film, resulting in an interference pattern that depends on the thickness of the film and the wavelength of the light.
Polarization interference: This occurs when light waves with different polarization orientations interfere with each other, resulting in changes to the polarization state of the light.
Multiple-beam interference: This occurs when more than two beams of light interfere with each other, resulting in complex interference patterns.
Holographic interference: This involves recording the interference pattern between two light waves on a photographic plate or other recording medium. The resulting hologram can be used to reconstruct the original wavefronts of the light.
Surface plasmon resonance: This occurs when light waves interact with surface plasmons, which are collective oscillations of electrons at the surface of a metal. The resulting interference pattern can be used for sensing applications.
Speckle interference: This occurs when coherent light scatters from a rough surface or through a turbid medium, resulting in a random interference pattern that depends on the exact configuration of the scattering medium.
"In physics, interference is a phenomenon in which two coherent waves are combined by adding their intensities or displacements with due consideration for their phase difference."
"The resultant wave may have greater intensity (constructive interference) or lower amplitude (destructive interference) if the two waves are in phase or out of phase, respectively."

"...adding their intensities or displacements with due consideration for their phase difference."
"Interference effects can be observed with all types of waves..."
"...for example, light, radio, acoustic, surface water waves, gravity waves, or matter waves as well as in loudspeakers as electrical waves."
