Multiple choice

Which of the following is not true regarding Beer-Lambert law?

  1. It defines relationship between Absorbance and Transmittance.

  2. Absorbance is the property of a sample while absorptivity is property of substance.

  3. Radiant energy will diminish in geometric or exponential progression.

  4. This law is true for all types of light.

  5. According to this law if 100% intensity is incident on first layer, then after 4th year the remaining intensity will be 6.25% (considering equal thickness layers)
