In Young's experiment, the pinholes are illuminated, by a monochromatic light of wavelength `5200 overset (@)(A)`. A screen is placed at 1 m from the slit. If the pinholes are 1.3 mm apart, find i)fringe width ii) the distance between the seventh bright band on one side and sixth dark band on the other side of the central bright band.

In a biprism experiment , the slit is illuminated by a light of wavelength of 5000 overset (@)(A) . The distance between the slit and eyepiece is 1 m . If the distance between the two virtual sources is 0.25 cm , then distance between fifth bright band on one side and the sixth dark band on the other sideof the central bright band will be

In a biprism experiement, the slit is illuminated by light of wavelength 4800 overset@A . The distance from the slit to the screen is 1 metre. If the distance between the two virtual sources is 0.3 cm, determine the distance between the 5th bright band on one side and 5th dark band on the other side.

Two straight and narrow parallel slits separated by 3mm are illuminated by a monochromatic light of wavelength 5460 overset (@)(A) . Interference fringes are obtained at a distance of 60 cm from the slits. Find the change in fringe width if the distance between the slits is i) increased by 1 mm and ii) decreased by 1mm.

In a biprism experiment the distance between the slit and the eyepiece is 100 cm. When a convex lens is introduced between the biprism and the eyepiece, images of the slit obtained in the two positions of the lens are 2 xx 10^-3 m and 4.5 xx 10^-3m apart.If the wavelength of light used is 6000 overset (@)(A) , find the distance between the fourth bright band on one side and fourth dark band on the other side of central bright band.

A biprism is placed 5 cm from slit illuminated by sodium light of wavelength 5890 overset (@)(A) The width of the fringes obtained on a screen 75cm from the biprism is 9.424 xx 10^-2 cm . What is the distance between two coherent sources ?

In a biprism experiment, the slit is illuminated by red light of wavelength 6400 overset (@)(A) and the crosswire in the eyepiece is adjusted to be at the centre of the 3rd bright band. By using blue light it is found that the 4th bright band is at the centre of the cross-wire. Find the wavelength of blue light.

In a biprism experiment, a source of light has a wavelength of 5500 overset@A . Calculate the change in fringe width, if the screen is at a distance of 1 m from the points which are 1mm apart.
