An absorbance reading of 2.0 means the sample is transmitting

  • A.10 per cent of the incident light
  • B.50 per cent of the incident light
  • C.99 per cent of the incident light
  • D.1 per cent of the incident light

Answer: D

An absorbance of two means the incident intensity has been divided by a hundred. Readings much above two are unreliable because so little light reaches the detector that stray light and noise begin to dominate the measurement.
