am I correct in thinking that if I multiply the lux over the area, from the lamp to the window, by the window's area I'll get the lumens through the window?
Light through window = (light from lamp)/(pi*distance2)*(window surface area)
Homework Statement
A lamp producing 1600 lumens is 16" away from a window of 0.015m^2 on a wall 0.14m^2, what is the amount of light through the window.
Homework Equations
lux = lumens/m^2
The Attempt at a Solution
Since there's no material in the window, shouldn't it be the full...
