Mark the statement true or false : (a) In Young's double slit expt, performed with a source of white light, only black and white fringes are observed. (b) Two slits in Young's double slit expt are illuminated by by two different sodium lamps emitting light of same wavelength. No interference pattern will be obtained.
The two slits in Young's double slit experiment are illuminated by two different sodium lamps emitting light of the same wavelength. No interference pattern will be observed on the screen.
Two slits 4.0 xx 10^(-6) m apart are illuminated by light of wavelength 600nm . What is the highest order fringe in the interference pattern?
Two independent sources of light will not produce steady interference pattern because
Two parallel slits 1 mm apart are illuminated with light of wavelength 5000 Å, from a single slit. Interference pattern is obtained on a screen placed at 1 m from the slits, what is the distance between the first bright bannd and the seventh dark band?
In YDSE setup slits are illuminated by a light of wavelength 4000Å and a light of unknown wavelength. It is observed that fourth dark fringe of known wavelength coincide with second bright fringe of unknown wavelength. Find the unknown wavelength.
(a) In Young's double slit experiment, the two slits are illuminated by two different lamps having same wavelength of light. Explain with reason, whether interference pattern will be observed on the screen or not. (b) Light waves waves from two coherent sources arrive at two points on a screen with path differences of 0 and lamda//2 . Find the ratio of intensities at the points.
In YDSE, two slits are separated by 3 mm and illuminated by light of wavelength 480 nm . The screen is 2 m from the plane of slits. Calculate the separation between 8th bright fringe and 3rd dark fringe observed on the same side of central bright fringe.
In Young's double slit experiment, if the two slits are illuminated with separate sources, no interference pattern is observed because
