What happen to the diffraction pattern when the slit separation increase or decrease?
When the slit separation increases, the diffraction pattern becomes wider, with narrower central maxima and weaker secondary maxima. Conversely, when the slit separation decreases, the diffraction pattern becomes narrower, with wider central maxima and stronger secondary maxima.

How does the interference pattern change when the number of slits in a diffraction grating is increased?
When the number of slits in a diffraction grating is increased, the interference pattern produced will have more distinct maxima and minima. The fringes will be narrower and more closely spaced, leading to a more defined and detailed pattern. Additionally, the overall intensity of the diffraction pattern will decrease due to light being spread over more orders.
Which device could produce a diffraction pattern consisting of a central bright fringe with parallel secondary fringes that decrease in intensity with increasing distance from the center of the screen?
A double-slit device would produce a diffraction pattern with a central bright fringe and parallel secondary fringes that decrease in intensity with distance from the center of the screen. This pattern is a result of interference of light waves passing through the two slits.
Does the intensity of light affect the diffraction pattern?
Yes, the intensity of light can affect the diffraction pattern. A higher intensity can result in a more pronounced diffraction pattern with increased visibility of interference fringes. Similarly, a lower intensity can lead to a dimmer diffraction pattern with less distinct fringes.
What should be approximate size of slit to observe diffraction?
The width of the slit should be on the order of the wavelength of the light being used for diffraction in order to observe the diffraction pattern clearly. This is known as the single-slit diffraction condition. The size of the slit also affects the angular spread of the diffraction pattern.
What is another term for fraunhofer diffraction?
Another term for Fraunhofer diffraction is far-field diffraction. This type of diffraction occurs when the distance between the diffracting object and the screen observing the diffraction pattern is much greater than the dimensions of the diffracting object.

How do you apply the diffraction of light in the real life?
The diffraction of light in the real life can be seen as a rainbow pattern on a DVD or CD. The closely spaced tracks function as diffraction grating. A credit card's hologram is another example diffraction light application in real life. The grating structure on the card produces the desired diffraction pattern.

Another term for Fraunhofer diffraction is far-field diffraction. This type of diffraction occurs when the distance between the diffracting object and the screen observing the diffraction pattern is much greater than the dimensions of the diffracting object.
What is wierl equation and its importance in interpretation of electron diffraction?
The Weir equation relates the crystal orientation, diffraction pattern geometry, and experimental conditions to the lattice parameters of a crystalline material in electron diffraction. It is important because it allows researchers to determine the crystal structure of a material by analyzing its diffraction pattern, providing critical information about the arrangement of atoms in the material.
What are the changes in diffraction pattern if monochromatic light is replaced by white light?
If monochromatic light is replaced by white light, the diffraction pattern will show a range of colors instead of a single color. This is because white light is a mixture of different wavelengths, each diffracting at different angles. The resulting diffraction pattern will be more colorful and dispersed compared to the pattern produced by monochromatic light.
What happens to the spacing of the bright spots in a diffraction pattern if the slit spacing becomes smaller?
As the slit spacing becomes smaller, the spacing of the bright spots in a diffraction pattern increases.
Is diffraction pattern itself is due to the interference of light?
Yes.
What are the characteristics of the FCC 111 diffraction pattern?
The FCC (face-centered cubic) 111 diffraction pattern is characterized by a series of sharp, evenly spaced diffraction spots arranged in a triangular pattern. These spots are located at specific angles and intensities, reflecting the crystal structure of materials with a face-centered cubic lattice.
What effect does an increase in the wavelength have on the interference pattern?
An increase in wavelength will cause the interference fringes to spread out since the distance between the fringes is directly proportional to the wavelength. This results in a larger separation between the bright and dark regions in the interference pattern.
