Answer:
The band gaps can be calculated via UV-Vis spectroscopy using Tauc Plots. Attached you can find one file for your assistance. Here we plot the graph between (ahv)1/2 on y-axis and hv on x-axis. a (alpha) is the absorbance calculated from UV and hv can be calculated by following way... hv = 1240/wavelength. Then you will extraplot the vertical sagments of the plot to intersect on x-axis where y-axis is zero. That value is your band gap. It might be direct or indirect depending upon the formula.
