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

Q. In a Young's double slit experiment, the separation between the slits is $0.15\text{mm}$. In the experiment, a source of light of wavelength $589\text{nm}$ is used, and the interference pattern is observed on a screen kept $1.5\text{m}$ away. The separation between the successive bright fringes on the screen is:

Q. In a Young’s double-slit experiment, the slits are separated by0.28 mm and the screen is placed 1.4 m away. The distance betweenthe central bright fringe and the fourth bright fringe is measured to be 1.2 cm. Determine the wavelength of light used in theexperiment.

Q. In Young's double slit experiment, the slits are separated by $0.56$ mm and the screen is placed $2.8$ cm away. The distance between the central bright fringe and the fifth bright fringe is $1.5$cm. Find the wavelength of light used.

Q. In Young's double- slit experiment, slits are separated by $0.5\text{mm}$ and the screen is placed $150\text{cm}$ away. A beam of light consisting of two wavelengths, $650\text{nm}$ and $520\text{nm}$, is used to obtain interference fringes on the screen. The least distance from the common central maximum to the point where the bright fringes due to both the wavelengths coincide are

Q. In Young's double slit experiment, blue-green light of wavelength 500 nm is used. The slits are 1.20 mm apart, and the viewing screen is 5.40 m away from the slits. The fringe width is:
