Light Intensity Model  

This simple model demonstrates the effect of distance and other variables on illumination.

STELLATM software is needed to view the model in Mac (hqx) format or PC format.

Distance_from_source(t) = Distance_from_source(t - dt) +
(velocity_of_probe) * dt
INIT Distance_from_source = 0.5
velocity_of_probe = .2
Illuminance = luminous_flux/(4*pi*Distance_from_source^2)
Watts = 100
luminous_flux = GRAPH(Watts)
