Interference of Light Waves and Young's Experiment

What is the importance of slits in Young$\text{'}$s double slit experiment?

In young's double slit experiment what will happen if monochromatic light is replaced by white light.

A laser beam is _____ light.

In YDSE using monochromatic light of wavelength $\raisebox{1ex}{$\mathrm{\lambda }$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$ the intensity of light at a point on screen is ${\mathrm{I}}_0$.

What is the intensity of light at a point where path difference is $\raisebox{1ex}{$\mathrm{\lambda }$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$.

A Young's double-slit experiment is performed with bi-chromatic light ($5500 \mathrm{Å}$ and $6000 \mathrm{Å}$) for $d=2 \mathrm{mm}$ and $D=1 \mathrm{m}$. The distance of the first complete maxima from the central maxima on the screen is $x \mathrm{mm}$. The value of $x$ correct to one decimal is,

In Young's double slit experiment, the slits are $2 \mathrm{mm}$ apart and are illuminated by photons of two wavelengths $750 \mathrm{nm} \mathrm{and} 950 \mathrm{nm}$. At what minimum distance from the common central bright fringe on the screen  $2 \mathrm{m}$ from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other?

Does diffraction take place at  the Young's double slit?

Two waves of equal amplitude and frequency interefere at a particular point. Calculate the ratio of intensities when both the waves reach in phase and when they reach with a ${90}^{\mathrm{o}}$ phase difference.

Obtain the equation for the bandwidth in the Young's double slit experiment.

In a Young's double slit experiment, the slit separation is doubled. To maintain the same fringe spacing on the screen, the screen to slit distance $D$ must be changed to:

What is bandwidth of interference pattern? 

In a Young's double slit experiment, the fringe pattern is observed on a screen placed at a distance $D$ from the slits. The slits are separated by a distance $d,$ and are illuminated by monochromatic light of wavelength $\lambda .$ The length of the slits is $\ell , \ell$ is usually much greater than $d.$ The slit width $w$ is extremely small, and the slits are otherwise identical.

Three equidistant slits are illuminated by a monochromatic parallel beam of light falling normally onto them. The screen is parallel to the plane of the slits and the slit separation $d<<D$. The observation point $P$ is directly opposite $A$. It is given that $BP-AP=\frac{\lambda }{4}, \lambda$ being the wavelength of light. Find the ratio of the intensity at $P$ when all slits are open to the intensity at $P$ when only one slit is open.

If the source of light used in a Young's double slit experiment is changed from red to violet,

Write down an analytical explanation of interference and write down conditions for constructive and destructive interference.

The intensity ratio of the maxima and minima in an interference pattern produced by two coherent sources of light is $9:1$. The intensities of the used light sources are in ratio $x:1$. Find $x$.

In a single slit diffraction pattern, the distance between the first minimum on the left and the first minimum on the right is $5 \mathrm{mm}$. The screen on which the diffraction pattern is displayed is at a distance of $80 \mathrm{cm}$ from the slit. The wavelength is $6000 \mathrm{\AA }$. The slit width is about $1.92\times {10}^{-n} \mathrm{m}$. Find the value of $n$.

In Young's double slit experiment the slits are $0.5\mathrm{mm}$ apart and interference is observed on a screen placed at a distance of $100\mathrm{cm}$ from the slits. It is found that the $9^{\text{th }}$ bright fringe is at a distance $8.835\mathrm{mm}$ from the second dark fringe on the same side of the fringe pattern. Find the wavelength of light used.

Monochromatic light from a narrow slit illuminates two narrow slits $0.3\mathrm{mm}$ apart producing an interference pattern with bright fringes $1.5\mathrm{mm}$ apart on a screen $75\mathrm{cm}$ away. Find the wavelength of the light. How will the fringe width be altered if

(a) the distance of the screen is doubled and

(b) the separation between the slits is doubled?

Two slits in Young's experiment have widths in the ratio $81:1$. What is the ratio of the amplitudes of light waves coming from them ?
