Figure 7.
The graph presents the relationship between transmittance percentage and wavelength measured in nanometres, ranging from 400 to 1000 nanometres. The horizontal axis indicates the wavelength, with marked increments, while the vertical axis shows transmittance percentage, labelled from 0 to 1.8. Four distinct lines represent different samples, the black line for C Z T S A D, the red line for C Z T S 340, the blue line for C Z T S 360, and the magenta line for C Z T S 380. Each line varies in transmittance levels across the wavelength range, with line trends observable throughout the plotted data. The visual characteristics include clear differentiation between the samples through the use of colour coding.Transmittance spectra plotted against wavelength
