Distance of `5^("th")` dark fringe from centre is 4 mm. If D = 2 m, `lambda=600` nm, then distance between slits is :

In the double-slit experiment, the distance of the second dark fringe from the central line are 3 mm . The distance of the fourth bright fringe from the central line is

In Young's double slit experiment the light emitted from source has lambda = 6500 Å and the distance between th two slits is 1 mm. Distance between the screen and slit is 1 metre. Distance between third dark and fifth birth fringe will be :

In Young's double slit experiment the light emitted from source has lambda = 6500 Å and the distance between th two slits is 1 mm. Distance between the screen and slit is 1 metre. Distance between third dark and fifth birth fringe will be :

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

Light of wavelength 5000 Å is incident on a double with and the interference fringes are formed on a screen plated at a distance of 1m from the slits. If the distance between the two consecutive dark bands is 1 mm, then the distance between the two slits is

Two slits are 1mm apart and a screen is placed at some distance. When the slits are illuminated with light of wavelength 500nm, fringe separation obtained on the screen is 0.5mm. What is the distance between the screen and the slits?

In Young's double slit experiment, the distance between two coherent sources is 1 mm and the distance between the slits and the screen is 1 m. If the 10th dark fringe is at a distance of 4.75 mm from the central bright fringe, calculate the distance of 5th bright fringe from the central bright fringe.
