In a Young's experiment,the width of the fringes objrtained with oligth of wavelength 6,000 overset@A is 2.0 mm.what will be the fringe width,if the entire apparatus is immersed in a iquid of erfractive index 1.33?

In Young's double slit experiment the width of the fringes obtained with ith of wavelength 4,500 overset@A is 1.8 mm.If the distance between the two slits is 0.3 mm,find the distance of the screen from the slits.What will be the fringe width,if the enitre apparatus is immersed in water of refraction index 4//3 .

Angular width of centrl maximum in the Fraunhofer diffraction pattern of a slit is measured.The slit is iluminated by igth of wavelength 6,000 overset@A .When the slit is illuminated by light of another wavelength,the angular width decreases y 30%.Calculate the wavelength of this light. The same decrease in the angular width of centrl maximum is obtained ,when the original appartus is immersed in a liquid.Fin refractive index of the liquid.
