Questions and Answers

Which of the following describes the process of measuring the absorbance or optical density of a solution using a photodetector system and a galvanometer?

  • The photodetector system measures the transmitted light, while the galvanometer measures the electrical signals
  • The photodetector system measures the reflected light, while the galvanometer measures the transmitted light
  • The photodetector system measures the transmitted light, while the galvanometer measures the absorbed light (correct)
  • The photodetector system measures the absorbed light, while the galvanometer measures the reflected light

    • What happens to the light when it reaches the Cuvette during the process of measuring the absorbance or optical density of a solution?

  • Some of the light is reflected, some part of the light is absorbed by the solution and the remaining part is transmitted through the solution (correct)
  • All of the light is absorbed by the solution
  • All of the light is transmitted through the solution
  • All of the light is reflected

    • What is the role of the galvanometer in the process of measuring the absorbance or optical density of a solution?

  • To measure the intensity of transmitted light
  • To measure the electrical signals sent by the photodetector system (correct)
  • To measure the intensity of absorbed light
  • To measure the intensity of reflected light
