Technician A says that the refractometer reading is determined at the point of the scale where the dark and light areas meet. Technician B says that the reading is determined by where a dial points on a scale. Who is correct

Respuesta :

lucic

Answer:

Technician B says that the reading is determined by where a dial points on a scale.

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
