Optical Microscopy and Specimen Preparation

Answer to Q2

 
  1. The specimen preparation is important in metallurgy because?
    a A poorly prepared specimen can damage the microscope.

    (Incorrect: unless the microscope is misused, a specimen will not damage the microscope.)
    b A poorly prepared specimen will distract from features on the specimen.

    Correct!
    c Only a well prepared specimen will reflect light.

    (Incorrect: the preparation does not cause the specimen to reflect light, but allows features to be picked out.)
    d A poorly prepared specimen will corrode, and the resulting images will be misleading.

    (Incorrect: a poorly prepared specimen will not corrode any faster than a properly prepared specimen.)
