A transparent glass plate of thickness 0.5 mm and refractive index 1.5 is placed infront of one of the slits in a double slit experiment. If the wavelength of light used is 6000 A^(@) , the ratio of maximum to minimum intensity in the interference pattern is 25/4. Then the ratio of light intensity transmitted to incident on thin transparent glass plate is

A thin glass plate of thickness t and refractive index mu is inserted between screen and one of the slits in a young's experiment. If the intensity at the centre of the screen is I, what was the intensity at the same point prior to the introduction of the sheet.

In YDSE when slab of thickness t and refractive index mu is placed in front of one slit then central maxima shifts by one fringe width. Find out t in terms of lambda and mu .

In double slit experiment what should be the width of each slit to obtain 10 maxima of the double slit pattern within the central maxima of single slit pattern with d=2 mm.

The intensity of the light coming from one of the slits in a Young's double slit experiment is double the intensity from the other slit. Find the ratio of the maximum intensity to the minimum intensity in the interference fringe pattern observed.

In a YDSE experiment the two slits are covered with a transparent membrane of negligible thickness which allows light to pass through it but does not allow water. A glass slab of thickness t=0.41 mm and refractive index mu_(g)=1.5 is placed infront of one of the slits as shown in the figure. The separation between the slits is d=0.30 mm . The entire space to the left of the slits is filled with water of refractive index mu_(w)=4//3 . A coherent light of intensity I and absolute wavelength lambda=5000Å is being incident on the slits making an angle 30^(@) with horizontal. If screen is placed at a distance D=1m from the slits, find ( a ) the position of central maxima. ( b ) the intensity at point O .

In YDSE , slab of thickness t and refractive index mu is placed in front of any slit. Then displacement of central maximu is terms of fringe width when light of wavelength lamda is incident on system is
