Write the conditions of maximum and minimum in diffraction pattern due to a single slit?
In diffraction pattern due to a single slit, the condition for a minimum is when the path length difference between two adjacent wavelets is a multiple of half the wavelength λ. This results in destructive interference where waves cancel each other out. The condition for a maximum is when the path length difference between two adjacent wavelets is an integer multiple of the wavelength λ, leading to constructive interference and a bright fringe.
What else can I help you with?
When does maximum diffraction occur?
Maximum diffraction occurs when the size of the diffracting opening or obstacle is comparable in size to the wavelength of the wave passing through it. This condition allows for the most bending or spreading of the wave, resulting in a more pronounced diffraction pattern.
What is effect in single slit diffraction of increasing the slit width?
Increasing the slit width in single slit diffraction results in a narrower central maximum and reduced overall diffraction pattern intensity. This is due to increased diffraction spreading caused by wider slit openings.
What happen to diffraction pattern if number of slits increased?
If the number of slits in a diffraction pattern is increased, the central maximum becomes narrower and the intensity of the secondary maxima decreases. The overall pattern becomes more defined and structured as more slits are added.
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 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.

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.
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.
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.
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.
Is diffraction pattern itself is due to the interference of light?
Yes.
