| Problem: A plane lambertian source | Prev topic | Next topic |
Consider a plane lambertian light source with a power output Φ. Prove that:
1. The intensity, Io, of that source (in the direction of the normal to the surface) can be expressed as follows:
| I0 = Φ / π | (1) |
2. The radiance, L, of that source (independent of direction in a hemisphere into which the source radiates) relates to the irradiance generated by that source as follows:
| L = E / π | (2) |
