From a carbon nanotube of $1 \,\mu m$ length and $1 \,nm$ radius. $10$ electrons have been removed. Assume the resulting positive charge to be distributed umforrnly over the surface of the tube. The energy of an electron moving in a stable circular orbit around the axis along the length of the tube is calculated by applying the Bohr model. Accordingly, the frequency of radiation required to excite an electron from its ground state to the next level is in the range of (charge of the electron, $e =1.60 \times 10^{-19} \,C$; mass of the electron, $m _{ e }=9.11 \times 10^{-31} \,kg$; Planck's constant, $h =6.63 \times 10^{-34} \,Js$; Permittivity of free space, $\left.\varepsilon_0=8.85 \times 10^{-12}\,F / m \right)$

In a double slit arrangement fringes are produced using light of wavelength 4800 Å. One slit is covered by a thin plate of glass of refractive index 1.4 and the other with another glass plate of same thickness but of refractive index 1.7. By doing so the central bright shifts to original fifth bright fringe from centre. Thickness of glass plate is
