Suppose white light falls on a double sllit but one slit is covered by a violet filter (allowing `lamda=400nm`). Describe the nature of the fringe pattern observed.

White light is used in a Young's double slit experiment. Find the minimum order of the violet fringe (lamda = 400 nm) which overlaps with a red fringe (lamda = 700 nm) .

In Young’s double slit experiment, the intensity of light coming from the first slit is double the intensity from the second slit. The ratio of the maximum intensity to the minimum intensity on the interference fringe pattern observed is

The intensity of the light coming from one of the slits in a Young's double slit experiment is double the intensity from the other slit. Find the ratio of the maximum intensity to the minimum intensity in the interference fringe pattern observed.

If white light is used in Young's double -slit experiment a) bright white fringe is formed at the centre of the screen b) fringes of different colours are observed on both sides of central fringe clearly only in the first order c) the first order violet fringes are closer to the centre of the screen than the first order red fringes d) the first order red fringes are closer to the centre of the screen than the first order violet fringes

In Young's double-slit experiment, the slit are 0.5 mm apart and the interference is observed on a screen at a distance of 100 cm from the slits, It is found that the ninth bright fringe is at a distance of 7.5 mm from the second dark fringe from the center of the fringe pattern. The wavelength of the light used in nm is

In Young's experiment, light of wavelength 600 nm falls on the double slits separated by 0.1 mm. What is the highest order of maximum intensity in the interference pattern obtained on a screen kept 3 m from the slits? How does the highest order change if the distance of screen from the slits is changed?

In a Young's double slit experiment, the source is white light. One of the holes is covered by a red filter and another by a blue filter. In this case

In a Young's double slit experiment, the source is white light. One of the holes is covered by a red filter and another by a blue filter. In this case

In a Young's double slit experiment performed with a source of white light, only black and white fringes are observed.

A Young's double slit apparatus has slits separated by 0.28 mm and a screen 48 cm away from the slits. The whole apparatus is immersed in water and the slits are illuminated by the red light ( lamda=700 nm in vacuum). Find the fringe-width of the pattern formed on the screen.
