Diffraction of Waves

Yellow light is used in a single slit diffraction experiment with slit width of 0.6 mm. If yellow light is replaced by X-rays, then the observed pattern will reveal,

Explain the effect of the diffraction of sound wave in our daily lives.

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 :

Which is the following colourful patterns is due to diffraction of light?

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.

The phenomenon of deviation of light when it goes over a sharp edge is called interference.

A diffraction pattern is obtained by making blue light incident on a narrow slit. If blue light is replaced by red light, then the diffraction bands _____.

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.

According to figure in an experiment electrons passes through a narrow slit of  width 'd' which is of the range of its D' Broglie wavelength and are detected on the screen at distance D from the slit. The intensity pattern on the screen is -

A diffraction grating having 7000 lines/cm is illuminated with a laser beam. If its second order spectral line is seen at ${62.4}^o,$ then what is the colour of the laser light?

Through a narrow slit of width 2mm, diffraction pattern is formed on a screen kept at a distance 2m from the slit. The wavelength of the light used is $6330 Å$ and falls normal to the slit and screen. Then, the distance between the two minimum on either side of the central maximum is

Light is incident normally on a diffraction grating through which first order diffraction is seen at ${32}^{\mathrm{o}}$ . The second order diffraction will be seen at

In Young's double slit experiment, distance between sources is $1 \mathrm{mm}$ and distance between source and screen is $1 \mathrm{m}$. If the fringe width is $6 \mathrm{mm}$, then wavelength of the light emitted from the source is

Distance between two slits is 0.03 cm. A screen is placed at a distance of 1.5 m. Interference pattern shows that fourth bright fringe is at 1 cm from the central maximum. Wavelength of light used is

Assertion: No interference pattern is detected when two coherent sources are infinitely close to each other in simple YDSE.

Reason: The fringe width is inversely proportional to the distance between the two slits in simple YDSE.
