Interference pattern Definition and 112 Threads

Homework Statement In a two - point in phase inteference pattern, what will happen to the number of nodal lines if the wavelength of the two sources increases? Justify your answer Homework Equations Not too sure if an equation is needed to answer this question The Attempt at a...

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...

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...

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...

Homework Statement The interference pattern on a screen 1.2 m behind a 710 line/mm diffraction grating is shown in Figure P22.45 (http://i137.photobucket.com/albums/q208/infinitbelt/p22-45alt.gif ), in which y1 = 52.3 cm and y2 = 107.6 cm. What is the wavelength of the light? 2. The...

Is there any way to perform the double slit experiment and see the interference pattern without using a laser? If so, what type of light do you need?

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?

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...

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...

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...

Heres the situation, You have 2 point sources producing circular water waves, in which the phase is adjustable. The question is In what respects does the interference pattern change and in what respects does it stay constant when the relative phase of your sources changes from 0 degrees to...

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...
