In Young’s Double-slit Experiment, The y-co-ordinates Of Central Maxima And 10th maxima Are 2 Cm And 5 Cm, Respectively. When The YDSE Apparatus Is Immersed In A Liquid Of Refractive Index 1.5, The Correspondingy-co-ordinates Will Be   

Light of wavelength λ = 5890 Ã… falls on a double-slit arrangement having separation d = 0.2 mm. A thin lens of focal length f = 1 m is placed near the slits. The linear separation of fringes on a screen placed in the focal plane of the lens is   

In Young’s double-slit experiment, the two slits act as coherent sources of equal amplitude A and of wavelength λ. In another experiment with the same setup, the two slits are sources of equal amplitude A and wavelengthλ, but are incoherent. The ratio of intensity of light at the mid-point of the screen in the first case to that in the second case is  

In Young’s double-slit interference experiment, if the slit separation is made threefold, the fringe width becomes 

Sources 1 and 2 emit lights of different wavelengths whereas 3 and 4 emit lights of different intensities. The coherence

If one of the two slits of a Young’s double-slit experiment is painted so that it transmits half the light intensity as the second slit, then  

A wave front AB passing through a system C emerges as DE. The systemC could be

Fig. shows a wavefront P passing through two systems A and B, and emerging as Q and then as R. The systems A and B could, respectively, be

Light waves travel in vacuum along the y-axis. Which of the following may represent the wavefront?
