In the hot-stage determination of the index of refraction of
glass samples a standard
reference material with the following behavior has been used.
Temperature (°C) nD Uncertainty
20 1.5154 0.0001
30 1.5106 0.0001
40 1.5058 0.0001
50 1.5009 0.0002
60 1.4961 0.0002
70 1.4912 0.0002
80 1.4864 0.0002
Two glass samples are being compared, K1 from the broken window at
a crime scene
and Q1 from the clothing of a suspect. Replicate measurements were
made on each
sample with the following results.
Below are the temperatures that were recorded.
K1 Replicate 1 Replicate 2 Replicate 3
T(disappears) 53.4 53.2 53.3
T(reappears) 56.1 56.3 56.0
Q1 Replicate 1 Replicate 2 Replicate 3
T(disappears) 56.1 55.8 55.9
T(reappears) 57.3 57.8 57.5
Determine the indices of refraction of the two glass samples. What
is your conclusion about the possible common origins of K1 and Q1?
Did they come from the same source? Why or why not?
