Consider a point M on the distant screen where there is a maximum due to the light from
If a third slit were added as shown at right, would there still be maximum constructive interference at point M? Explain.
Suppose that more identical slits were added with till adjacent slits a distance d apart.
Would there still be maximum constructive interference at point M? Explain.
Let
For three or more evenly-spaced slits, what is the corresponding condition for locations of maximum constructive interference? Express this condition in terms of
We will call a location at which light from all of the slits is in phase a principal maximum.

- A simple cubic crystal is illuminated with X- ray of wavelength 0.09 nm at a glance angle. The crystal is rotated and the angles at which Bragg reflection occurs are measured. 1. Which set of crystal plane will give the smallest angle for first - order reflection? Explain in details your answer. 2. If this angle is 8.9°, determine the spacing between these planes. 3. At what angle will first-order reflection be obtained from the (110) crystal planes? Will there be any higher order reflection from this plane?arrow_forwardSuppose that the simulated light source was polychromatic, with both a red and a yellow component, as shown on the right. How easy would it be to identify the positions (yP ) of the separate red and yellow interference maxima? Can you think of a change in the appearance of the interference pattern of each individual wavelength that, were it to happen, would help to distinguish the red from the yellow peaks?arrow_forwardFor an aperture of width 1mm and using light of wavelength of 633 nm, estimate the distance from the aperture at which the Faunhofer approximation would be appropriate. a. Under the Fraunhofer condition, what would be the angle of the first minimum? b. If the screen is 1m away, how far from the central maximum would the first minimum be located?arrow_forward
- Reflection by thin layers. In the figure, light is incident perpendicularly on a thin layer of material 2 that lies between (thicker) materials 1 and 3. (The rays are tilted only for clarity.) The waves of rays r, and r, interfere, and here we consider the type of interference to be either maximum (max) or minimum (min). The table below provides the indexes of refraction n,, n2, and n3, the type of interference, and the thinlayer thickness L in nanometers.
