For small values of 
When Light diffracts from each
slit, These waves overlap and interfere constructively to give
maximum intensity or bright lines and destructively to give zero
intensity or dark regions sinusoidally.

Predict and Explain Task: Below is the light patterm produced by a laser projected through a single slit. The wavelength is 500nm. The width ofthe slit is 2.00μm. Now, the single slit is replaced with a double slit. The slits are much narrower, but the distance between the slits is 2.00μm. Nothing else in the experiment has changed. Draw what the new pattern will look like Please carefully explain your reasoning

Physics 8B Lab 8-Diffraction rev 4.0 Part I: Single-Slit Diffraction Here light shines on a single narrow slit of width a. The name may suggest only one wave passes through the slit, but that is misleading. The slit will be treated not as a single point source, but rather as having some finite size. So what you are studying is the interaction between all the waves that pass through this narrow opening. They will result in a diffraction...

The graph below represents the intensity of light plotted for
different positions on a screen. The pattern was created by a
single frequency of light (wavelength λ) shining through a pair of
slits. The peaks represent bright fringes or spots. The valleys
represent dark spots. Label each of the following statements as
true or false.
Position C on the
screen is two wavelengths further from one slit than the other.

An experiment is set-up with a monochromatic light source, a double slit, and a screen, similar to what is shown on page 7-2 of your lab manual. The experimenter measures and sketches the intensity pattern shown below. The scale along the bottom of the figure is in centimeters. What is the distance 2x3 between the third maxima in the intensity pattern? Note: the central peak is the ?zeroth maximum?, the two peaks closest to this on either side are the...
