Question

multiple choice listen analyze the graph below. which of the following wavelengths of light does chlorophyll absorb best? absorption spectrum of chlorophyll a 100 absorption (%) 0 400 500 600 700 wavelength (nm)

Explanation:

To solve this, we analyze the absorption spectrum of chlorophyll A. The graph shows two main peaks: one in the blue - violet range (around 400 - 450 nm) and one in the red range (around 650 - 700 nm). Chlorophyll absorbs light most effectively at these wavelengths. Typically, chlorophyll a has a strong absorption peak around 430 nm (blue - violet) and around 660 nm (red). So the wavelengths where chlorophyll absorbs best are around 430 nm (blue - violet) and 660 nm (red). If we consider common options (even though not listed here, from knowledge of chlorophyll absorption), the best - absorbed wavelengths are in the blue - violet (around 400 - 450 nm) and red (around 650 - 700 nm) regions. For example, a common answer would be around 430 nm (blue - violet) or 660 nm (red) as the wavelengths where chlorophyll absorbs light best.

The absorption spectrum of chlorophyll A has two main peaks. One is in the blue - violet range (around 400 - 450 nm) and the other is in the red range (around 650 - 700 nm). Chlorophyll absorbs light most effectively at these wavelengths.

Answer:

The wavelengths at which chlorophyll absorbs best are around 430 nm (blue - violet) and 660 nm (red) (or specific values like 430 nm and 660 nm depending on the context of the question's options).
