In a Young's experiment, one of the slits is covered with a transparent sheet of thickness `3.6xx10^(-3)cm` due to which position of central fringe shifts to a position originally occupied by 30th fringe. If `lambda=6000 Å`, then find the refractive index of the sheet.

In the Young's experiment, one of the slit is covered with a transparent sheet of thickness 3.6xx10^(-3) cm due to which position of central fringe shifts to a position originally occupied by 30th bright fringe. The refractive index of the sheet, if lambda=6000Å is

In a young's double slit experiment, one of the slits is covered by a glass sheet of thickness 2.5xx10^(-5) m. Due to this, the position of the central bright fringe is shifted to position originally occupied by the 30th bright fringe. If lamda=5000 Å, then the refractive index of glass is

When a thin sheet of a transparent material of thinkness 7.2xx10^(-4) cm is introduced in the path one of the interfering beams, the central fringe shift to a position occupied by the sixth bright fringe. If lambda=6xx10^(-5) cm, find the refractive index of the sheet.

When one of the slits of Young's experiment is covered with a transparent sheet of thickness 4.8mm , the central fringe shifts to a position originally occupied by the 30th bright fringe. What should be the thickness of the sheet if the central fringe has to shift to the position occupied by 20th bright fringe?

In young's experiments ,the source of red light of wavelength 7xx10^(-7)m when a thin glass plate of refrative index 1.5 at this wavelength is put in thepath of one of the interfering beams,the central bright fringe shifts by 10^(-3) m to the position previously occupied by the 5th bright fringe,Find the thickness of the plates. When the sources is now change to green light of wavelenght 5xx10^(-7) m ,the central fringe shifts to a position initially occupied by the 6th bright fringe due to red light,Find the refractive index of glass for the green light .Also estimate the changes in fringe width due to the change in wavekength

In Young's experiment, the source is red light of wavelength 7xx10^(-7)m . When a thin glass plate of refractive index 1.5 at this wavelength is put in the path of one of the intering beams, the central bright fringe shiffts by 10^(-3)m to the position previously occupied by the 5^(th) bright fringe. When the source is now changed to green light of wavelength 5xx10^(-7)m , the central fringe shifts to position initially occupied by the 6^(th) bright fringe to red light. Find the refractive index of glass for green light.

In a double-slit experiment, fringes are produced using light of wavelength 4800A^(@) . One slit is covered by a thin plate of glass of refractive index 1.4 and the other slit by another plate of glass of double thickness and of refractive index 1.7. On doing so, the central bright fringe shifts to a position originally occupied by the fifth bright fringe from the centre. find the thickness of the glass plates.

Monichromatic lightof wavelenght 600 nm is used ina Young's double slilt experient. One of the slits is covered by a transparent sheet of thicknes 1.8xx10^-5 m made of a material of refractive index 1.6. How many fringe will shift due to the introduction of the sheet?

A thin sheet of glass (mu=1.520) is introduced normally in the path of one of the two interfering waves. The central bright fringe is observed to shift to position originally occupied by the fifth bright fringe. If lambda=5890Å . Find the thickness of the glass sheet.
