Position Of Bright And Drak Fringe In Ydse

In YDSE experiment a uniform intensity light beam is incident on slit plane which has two slits having width ratio 9 : 4 . Find the ratio of intensities of bright and dark fringes on screen. [25]

Light of wavelength 580 nm is incident on a slit having a width of 0.300 nm The viewing screen is 2.00 m from the slit. Find the positions of the first dark fringe and the width of the central bright fringe.

Assertion : In YDSE bright and dark fringe are equally spaced. Reason : It only depends upon phase difference.

Light of wavelength 6000Å is incident on a slit of width 0.30 mm. The screen is placed 2 m from the slit. Find (a) the position of the first dark fringe and (b). The width of the central bright fringe.

In the figure is shown Young's double slit experiment. Q is the position of the first bright fringe on the right side of O. P is the 11^(th) bright fringe on the other side, as measured from Q. If the wavelength of the light used is 600 nm . Then S_(1)B will be equal to

In YDSE, what is the ratio of fringe width for bright and dark fringes ?

Shape Of Interference Fringes In Ydse

In YDSE, the central bright fringe produced by light of wavelength 5600 Å shifts to the position of 5th bright fringe when a thin transparent film of refractive index 1.28 is introduced in the path of light from one of the two slits. Find the thickness of the film.
