3- Calculations The multimeter resolution range for resistance measurements is from 0.10 to 40 MQ. Based on this knowledge, provide upper or lower resistance values for copper, ZnSe and glass. Could

you calculate the conductivity of these materials from your resistance measurements? Explain. The cut-off wavelength of a material corresponds to the lowest light energy that can promote an electron across the band-gap E₁. Accordingly, use your Transmission spectrum to provide an estimate of the band-gap energy E, for zinc selenide. E₂ hc == Your report should include: 1- A table of resistance values in 2 for each materials. 2- A discussion of the connection between resistance and conductivity. 3- A discussion of the correlation between the bonding type and the electrical resistance for each material. In particular, discuss the case of zinc selenide. 4- An Excel graph of Transmission spectra for each material. 5- A discussion of the correlation between the bonding type and the optical transparency for each material. 6- An estimate of the band-gap energy E, for zinc selenide including details of your calculations. 7- A discussion of why you could not measure the cut-off wavelength for silicon of for the glass slide.
