The incident light on a Yound's experiment has wavelengths `400 nm` and `600 nm`. The distance between the two interfering sources is 2 mm and screen is at a distance of 1 m. The position from central fringe, where bright fringes of two wavelengths coincide first is at a distance of

A beam of light consisting of two wavelengths 500 nm and 400 nm is used to obtain interference fringes in Young's double slit experiment. The distance between the slits is 0.3 mm and the distance between the slits and the screen is 1.5 m. Compute the least distance of the point from the central maximum, where the bright fringes due to both the wavelengths coincide.

The distance between two coherent sources is 1 mm. The screen is placed at a distance of 1 m from the sources. If the distance of the third bright fringe is 1.2 mm from the central fringe, the wavelength of light used is

The distance between two coherent sources is 1 mm. The screen is placed at a distance of 1 m from the sources. If the distance of the third bright fringe is 1.2 mm from the central fringe, the wavelength of light used is

A beam of light consisting of two wavelengths, 650 nm and 520 nm,is used to obtain interference fringes in a Young experiment.-What is the least distance from the central maximum where the bright fringes due to both the wavelengths coincide?

Youngs double slit experiment is performed with light of wavelength 550 nm. The separation between the slits is 1.10 mm and the screen is placed at a distance of 1 m. The distance between the consecutive bright and dark fringes is

With two slits spaced 0.2 mm apart and a screen at a distance of 1 m, the third bright fringe is found to be at 7.5 mm from the central fringe. The wavelength of light used is
