| Problem: Decadic absorption coefficient |
The decadic absorption coefficient (see Absorption coefficient), a10, of a medium in which light scattering is negligible can be defined as follows:
| a10 = - (1 / z) log10[Φ(z) / Φ(0)] | (1) |
where z is the distance in a uniform medium and Φ(z) is the power of light in a collimated beam. On the other hand, the absorption coefficient for such a medium can be defined as follows:
| a = - (1 / z) ln[Φ(z) / Φ(0)] | (2) |
Derive the relationship between a10 and a, given that the distance unit is the same.
