In fresnel's biprism `(mu=1.5)` experiment, the distance between source and biprism is 0.3 m and that between biprism and screen is 0.7 m and angle of prism is `1^(@)`. The fringe width with light of wavelength 6000 Å will be

In Fresnel's biprism (mu=1.5) experiment the distance between source and biprism is 0.3m and that between biprism and screen is 0.7m and angle of prism is 1^@ . The fringe width with light of wavelength 6000Å will be

In fresnel's biprism experiment the distance between the source and the screen is 1 ma nd that between the screen is 1 m and that between the source and biprism is 10 cm. the wavelength of light used is 6000Å. The fringe width obtained is 0.03 cm and the refracting angle of biprism is 1^(@) then calculate the refractive index of the material of biprism.

In YDSE, separation between slits is 0.15 mm, distance between slits and screen is 1.5 m and wavelength of light is 589 nm, then fringe width is

In YDSE, separation between slits is 0.15 mm, distance between slits and screen is 1.5 m and wavelength of light is 589 nm, then fringe width is

In Young's experiment the distance between two slits is d/3 and the distance between the screen and the slits is 3D. The number of fringes in 1/3 metre on the screen, formed by monochromatic light of wavelength 3lambda , will be:

In YDSE the distance between the slits is 1mm and screen is 25nm away from intensities IF the wavelength of light is 6000A the fringe width on the screen is

In Young's double slit experiment, the distance between two sources is 0.1mm . The distance of screen from the sources is 20cm . Wavelength of light used is 5460Å . Then angular position of the first dark fringe is

A beam of light consisting of two wavelength , 6500 A^(@) and 5200 A^(@) is used to obtain interference fringes in a Young's double slit experiment (1Å = 10^(-10)m) . The distance between the slits 2.0 mm and the distance between the plane of the slits and the screen is 120 cm. Find the distance of the third bright fringe on the screen from the central maximum for the wavelength 6500 Å .

In the Young's double slit experiment, the spacing between two slits is 0.1mm . If the screen is kept at a distance of 1.0m from the slits and the wavelength of ligth is 5000Å , then the fringe width is

In a Fresnel biprism experiment, the two positions of lens give separation between the slits as 16cm and 9cm respectively. What is the actual distance of separation?
