1)They are very reliable because they are almost always accurate.All science in the courtroom has to be verified in order to be used in the court to prove that their tests are accurate and reliable and can be used as an evidence in court. Reliability is measured by how much your machines have been validated ,if a forensic scientist in a court say the evidence is true but did not have a proper reliability , than people can question how true this test can actually be. Hard science is consisted of chemistry,biology and physics are the most reliable evidence.
2)The reliability of the analytical science in the courtroom is growing. This is because of the fact that analytical science involves comparison between the characteristics and features of the suspected specimens with those obtained from the criminals or victims. The analytical science plays an important role in proving a fact that a crime has been committed, the place of crime and establishing the identity of the culprit.

Answer:
Explanation:
This type of determination compares a known sample to a glass fragment to see if the two samples came from the same source.
Glass can be made from a variety of different materials that differ from batch to batch. The presence of the different materials in the glass makes it easier to distinguish one sample from another. Also, the properties of glass can vary depending upon the temperature the glass is exposed to during manufacturing. Basic properties, such as color, thickness, and curvature, can also help to identify different samples of glass just by looking at them. Optical properties, such as refractive index (RI), are defined by various manufacturing methods. RI is the manner in which light passes through the glass. This can be measured easily even on small fragments of glass. These properties help to indicate that two samples of glass could be from the same source.
