<br>5 - The flashlight is a bright white color and is emitting light across the entire visible spectrum and, maybe, a significant amount to either side of the visible spectrum as well (assuming the light is produced by a heated filament. Less so with an excited gas or white LEDs) What does the absorption spectrum of a leaf look like? The lower the percentage of light absorbed by the leaf, the stronger the flashlight has to be to dump enough energy into it. {{unsigned ip|198.41.235.185}} | <br>5 - The flashlight is a bright white color and is emitting light across the entire visible spectrum and, maybe, a significant amount to either side of the visible spectrum as well (assuming the light is produced by a heated filament.
