A monochromatic laser beam illuminates a double-slit apparatus with a slit separation of 0.6x10^(-3) m. The interference pattern is formed on a screen that is 1.2 m away from the slits. If the distance between the eighth bright fringe and the second bright fringe on the screen is 6x10^(-3) m, what is the wavelength of the laser beam (measured in nm)? 1 nm = 1x10^(-9) m.

Problem a Find the conductivity \(\sigma\) for silicon (Si) at room temperature considering that the conduction is due to both electrons and holes in equal numbers. The electrons and holes mobilities are \(\mu_e = 0.13\) m²/V.s and \(\mu_h = 0.05\) m²/V.s. Since Si is a semiconductor, the number of carriers needs to be estimated from the following equation: \(n = 2.51 \times 10^{25} e^{-E_g/2k_BT}\) carriers/m³ where \(E_g = 1.1\) eV is the gap energy, \(k_BT = 0.025\) eV at room temperature and \(n_e = n_h = n\). b Calculate the occupation probability \(f(E)\), the probability that a state will be occupied, at 293 K for a state at the bottom of the conduction band in silicon. The energy of the gap is \(E_g = 1.1\) eV and assume that the Fermi energy lies in the middle of the gap. c Silicon's conductivity increases greatly when is irradiated with electromagnetic waves of a certain wavelength. What is this wavelength?
