Assuming that each pane blocks an equal amount of light, the amount of light that passes through 10 panes is the same as the product of the percentage of light that passes through one pane 10 times.
If, for example, each pane blocks 10% of the light, then the percentage of light that passes through one pane is 100% - 10% = 90%. Therefore, the percentage of light that passes through 10 panes would be:
90% x 90% x 90% x 90% x 90% x 90% x 90% x 90% x 90% x 90% ≈ 34.87%
So, if each pane blocks 10% of the light, approximately 34.87% of the light will pass through 10 panes. However, the actual percentage of light that passes through 10 panes will depend on the percentage of light that is blocked by each pane.
