Answer:
Technician B says that the reading is determined by where a dial points on a scale.
Step-by-step explanation:
A refractometer is a devise used by scientists to gauge a liquids index of refraction.
The refractive index of a liquid is the ratio of light velocity of a specific wavelength in air to its velocity in the substance in evaluation.
The steps of reading a measurement are;
- point the front of the refractometer towards the light source and view into the eyepiece
- You will see the line outlined at a different point on the refractometer's internal index
- Read the point on the index at which the line falls
