Problem 3 You can learn a lot about materials by shining a range of different light wavelengths through them and measuring the intensity of light that comes through. If I shine light from 300- 1600 nm into a material and note that absorption peaks at 1450 nm and then drops at longer wavelengths: (a) Calculate the band gap (b) Determine whether or not the material would be transparent or opaque to white light (c) Do you think it is a metallic or nonmetallic material
