In a double slit experiment, instead of taking slits of equal widths, one slit is made twice as wide as the other. Then in the interference pattern

In the Young\'s double slit experiment, for which colour the fringe width is least?

In a Young\'s double slit experiment, the separation of the two slits is doubled. To keep the same spacing of fringes, the distance D of the screen from the slits should be made

If white light is used in the Newton\'s rings experiment, the colour observed in the reflected light is complementary to that observed in the transmitted light through the same point. This is due to

An interference pattern was made by using red light. If the red light changes with blue light, the fringes will become

If a white light is used in Young\'s double slit experiments then a very large number of coloured fringes can be seen

In Young\'s double slit experiment, the central bright fringe can be identified

In Young\'s double slit experiment, the wavelength of the light used is doubled and distance between two slits is half of initial distance, the resultant fringe width becomes

In a Young\'s double slit experiment, the source illuminating the slits is changed from blue to violet. The width of the fringes

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
