Question
**Absorption Spectrum of Chlorophyll** **3. Collected Data:** The table below presents the absorption spectrum data for chlorophyll across various wavelengths: | nm | ABS | nm | ABS | nm | ABS | |-----|------|-----|------|-----|------| | 400 | 0.087 | 500 | 0.024 | 600 | 0.039 | | 410 | 0.124 | 510 | 0.014 | 610 | 0.040 | | 420 | 0.125 | 520 | 0.011 | 620 | 0.041 | | 430 | 0.160 | 530 | 0.018 | 630 | 0.042 | | 440 | 0.233 | 540 | 0.017 | 640 | 0.074 | | 450 | 0.150 | 550 | 0.016 | 650 | 0.100 | | 460 | 0.143 | 560 | 0.015 | 660 | 0.155 | | 470 | 0.109 | 570 | 0.011 | 670 | 0.025 | | 480 | 0.076 | 580 | 0.025 | 680 | 0.029 | | 490 | 0.035 | 590 | 0.035 | 700 | 0.004 | **4. Graphing Instructions:** Create a graph representing the absorption spectrum for chlorophyll by plotting the above data. Ensure that you label the X-axis with "Wavelength (nm)" and the Y-axis with "Absorbance (ABS)". Title your graph appropriately, for example, "Absorption Spectrum of Chlorophyll". **5. Analysis:** Discuss the findings based on the data collected in the table. Consider the following points: - What does the Absorbance (ABS) tell you about how chlorophyll absorbs light at various wavelengths and colors? - How do these results relate to the typical absorption spectrum of chlorophyll, with known peaks in the blue (around 430 nm) and red (around 660 nm) regions? - Draw conclusions from this data using the graph created earlier in the lab. What do these observations imply about the efficiency of photosynthesis at different wavelengths? By analyzing these data points,
