Diffraction of Light

What is the condition for diffraction from an obstacle?

How diffraction occurs from an obstacle?

 In Fraunhofer's Diffraction pattern,the intensity of centra maximum is higher than secondary maximum.

Why sound diffraction is more pronounced than light diffraction?

Explain diffraction of Sound Waves and Its Importance in Daily Life.

How the diffraction pattern from the edge of an object is different from the diffraction pattern around the point size object.

How the diffraction pattern from the edge of an object is different from the diffraction pattern around the object.

First diffraction minimum due to a single slit of width $1.0\times {10}^{-5} \mathrm{cm}$ is at ${30}^{\circ }$. Then the wavelength used is :

A beam of light of wavelength $600 \mathrm{nm}$ from a distant source falls on a single slit $1.0\mathrm{mm}$ wide and the resulting diffraction pattern is observed on a screen $2 \mathrm{m}$ away. What is the distance between the first dark fringe on either side of the central bright fringe?

Discuss diffraction at single slit and obtain condition for ${\mathrm{n}}^{\mathrm{th} }$minimum.

Light of wave length $5500 \mathrm{\AA }$ is incident perpendicularly on a linear hole of width $22\times {10}^{–7} \mathrm{cm}$. Find out angular position of first two minima situated on both sides of central maxima.

Represent graphically the intensity distribution in the case of diffraction due to single slit.
