Hi,
I’ve got a general question about wave-particle duality, and the experiments done with slits.
When a laser is beamed through a small slit, we get a diffraction pattern. This pattern is interesting because it contains dark bands.
When it comes to explaining the existence of...
Optics Q!: Diffraction Pattern from a Ronchi Ruling
Hey everyone,
allow me to explain the experiment I'm working on before I get into my question. The experiment has light passing through a slit at the focal point of a lens. Since the light is at the focal point, theoretically it should...
I want to find which elements and planes the intensity peaks in this graph comes from. The X-rays in the diffractometer are have a wavelength of 0.709 Å. The 2 \theta values for the peaks (including double peaks) are: 11.84, 19.56, 20.04, 23.28, 33.88 and 39.16.
Nickel, iron, silicon...
Homework Statement
The central bright fringe in a single slit diffraction pattern from light of wavelength 412 nm is 1.9 cm wide on a screen that is 1.05 m from the slit.
How wide is the slit?

hello
I wonder if the diffraction pattern after Laserlight going thru a grating pattern (say 10 slots) has anything to do with the Fourier transform of the grating pattern.
I am not a physicist, but have some knowledge of Fourier math.
I think the spatial frequencies of the grating pattern...
In the famous two-split experiment in your freshman college class, you learn that shining a light at a wall with two narrow slits causes a diffraction pattern.
Something that's always bothered me is in these ideal setups, we always assume the wall is a continuous barrier to the light. But the...
hi everybody.
I have a problem in finding the width of central maximum in a single slit diffraction pattern. theoritically, we say it is the distance between the two first minima on either sides of the central maxima. i feel this calculation leads to the width of central maxima+half minima on...
Help with printing a string
I have a theoretical plot for the fresnel diffration pattern, however i want maple to show the values plotted on the x and y cordinates. How do i do this. Please explain in simple terms
heres my code

Diffraction pattern??
This isn't a homework problem, but something I noticed and would like to understand. Hopefully I have posted this in the right area:
I have a window that faces west. The other day I noticed a perfectly circular patch of light (several inches in diameter) on the wall...
Thank you for your insights on this.
Suppose our kitchen table has a double glass top. Here and there it produces Newton's rings type interference patterns.
I understand that by reverse transforming an interference pattern you can recover an image.
If I were to somehow do this...
Is the diffraction pattern of two recti-linear slits or an annular aperture due to the photons that diffract off the atoms located in the topmost atomic layers of the slit itself?
If my explanation of the cause of diffraction patterns is true, then what are the ramifications?
A diffraction pattern is produced on a screen 140 cm from a single slit using monochromatic light of wavelength 500 nm. The distance from the center of the central maximum to the first order maximum is 3 mm. Calculate the slit width (assume first order maximum is halfway between the first and...
Hello ,
How r u .
i know the formula of SINGLE SLIT DIFFRACTION PATTERN but i don,t know the method ho to drive it.Can any GENIUS tell me the procedure to drive this equation.
DERIVATION starts in this manner:
let d the separation b/w any two consecutive slits,D=(N-1)
r1 is the...
I'm stuck on the following question:
the diffraction patterns produced when Xrays of wavelength 46.8pm or electrons of energy 688eV are scattered from the same specimen of aluminium are found to be essentially identical. Use this information to determine the value of Planck's constant, h...
