What is Interference pattern: Definition and 114 Discussions

In physics, interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude. Constructive and destructive interference result from the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves, gravity waves, or matter waves. The resulting images or graphs are called interferograms.

    Find Lambda_2 for Double Slit Interference Pattern

    Homework Statement A laser with wavelength d/8 is shining light on a double slit with slit separation d. This results in an interference pattern on a screen a distance L away from the slits. We wish to shine a second laser, with a different wavelength, through the same slits. What is the...

    Constructing a Standing Wave Interference Pattern

    Hi, the question was, "Suppose that the wave represented by the graphs interfered with its OWN reflection. Sketch one standing wave interference pattern you would expect to observe. On your sketch, indicate the amplitude of each supercrest and supertrough, and the internodal distance (using...

    Light Bulbs Interference Pattern - Vey Easy Multiple Choice

    Homework Statement Two small light bulbs are placed close together to try and create an interference pattern. This pattern would not be visible due to the: a. random phase differences between the light waves from the two sources b. very high speed of the light waves c. diffraction of the...

    Double Slit Interference Pattern

    It is said that even if we were to send single electrons through a double slit or a single slit we would see an interference pattern on the screen (as long as we don't setup a detector to tell us which path the electron took). How do you send SINGLE electrons into a slit? There are electrons...

    Interference pattern of light through a grating

    can someone please solve this equation Monochromatic light with a frequency of 6.50 x 10^14 hz is directed on a diffraction grating ruled with 4.00 x 10^4 lines/m. An interference pattern is produced on a screen 1.10m from the grating. How far is the 1st order maximum from the central maximum?

    How Does Light Diffract Around a Tiny Spherical Bead?

    A tiny spherical bead of steel bead is suspended by a special transparent thread that does not diffract light so that it has no effect on the interference pattern of the bead. Draw to scale the interference pattern created by the bead. The bead has a diameter of 0.13 mm. Include only the...

    Understanding Interference Patterns in Three-Slit Diffraction

    Anyone can help me on this one. A plane wave of wavelength \lambda= 550 nm is incident normally on an opaque screen with three narrow parallel slits separated by distance a= 2.3 mm. An interference pattern is observed on the other side of the screen at a large distance from it. (a)At what...

    Interpreting Interference Pattern Shift in Double Slit Experiment

    Here's the question, A double slit experiment uses a helium-neon laser with a wvaelength of 633nm and a slit separation of 0.120 mm. When a thin sheet of plastic is placed in front of one of the slits, the interference pattern shifts by 5.50 fringes. When the experiment is repeated under...

    2 frequencies within an interference pattern

    Hi, short question. What would be the effect of 2 sources both transmitting 2 different frequencies if placed in a way that forms an interference pattern. ie. 2 aerials places parallel X meters apart transmitting in the same direction at 2 different frequencies per aerial. Sorry if i...
