In a Young's double slit experiment, slits are separated by `0.5 mm` and the screen is placed `150 cm` away. A beam of light consisting of two wavelengths, `650 nm` and `520 nm`, is used to obtain interference fringes on the screen. The least distance from the commom central maximum to the point where the bright fringes fue to both the wavelengths coincide is

In Young's double slit experiment slits are separated by 2 mm and the screen is placed at a distance of1.2 m from the slits. Light consisting of two wavelengths 6500Å and 5200Å are used to obtain interference fringes. The the separation between the fourth bright fringes the two wavelength is

In a Young's double slit experiment two slits are separated by 2 mm and the screen is placed one meter away. When a light of wavelength 500 nm is used, the fringe separation will be:

A beam of light consisting of two wavelength 800 nm and 600 nm is used to obtain the interference fringes in YDSE on a screen held 1.4 m away. If the two slits are separated by 0.28 mm , calculate the least distance from thecentral bright maximum, where the bright fringes of the two waveength coincide.

(a) In Young's double slit experiment, derive the condition for (i) constructive interference and (ii) destructive interference at a point on the screen. (b) A beam of light consisting of two wavelengths, 800 nm and 600 nm is used to obtain the interference frings in a Young's double slit experiment on a screen placed 1.4 m away. If the two slits are separated by 0.28 mm, calculate the least distance from the central bright maximum where the bright fringes of the two wavelengths coincide.

In Young's double slit experiment the slits are separated by 0.24 mm. The screen is 2 m away from the slits . The fringe width is 0.3 cm. Calculate the wavelength of the light used in the experiment.

In a Young's double slit experiment, the slit separation is 1mm and the screen is 1m from the slit. For a monochromatic light of wavelength 500nm , the distance of 3rd minima from the central maxima is
