What are the physical properties of glass?
Transparency, flexibility, low melting point
Transparency, softness, low melting point
Transparency, hardness, brittleness, high melting point
Transparency, flexibility, high melting point
What are the different types of glass fractures?
linear fractures, spiral fractures, and transverse fractures
tensile fractures, shear fractures, and bending fractures
compression fractures, torsion fractures, and flexion fractures
radial fractures, concentric fractures, and impact fractures
How is glass evidence used in forensic investigations?
Glass evidence is used to determine the type, source, and role of glass in a crime.
Glass evidence is used to determine the temperature at which the crime was committed.
Glass evidence is used to identify the fingerprints of the suspect.
Glass evidence is used to analyze the DNA of the victim.
What are the steps involved in glass comparison and identification?
Visual examination only
Comparison with other materials
Visual examination, measurement of physical properties, chemical analysis, and comparison with reference samples.
Measurement of chemical properties
Which physical property of glass is used to determine its refractive index?
hardness
speed of light
color
density
What is the difference between radial and concentric fractures in glass?
Radial fractures and concentric fractures are the same thing.
Radial fractures form straight lines, while concentric fractures form circles around the point of impact.
Radial fractures radiate outward, while concentric fractures form circles around the point of impact.
Radial fractures form circles around the point of impact, while concentric fractures radiate outward.
How can glass evidence help in determining the point of impact in a crime scene?
By analyzing the direction and pattern of shattered glass fragments.
By analyzing the chemical composition of the glass fragments.
By measuring the thickness of the glass fragments.
By examining the color of the glass fragments.
What is the significance of density in glass comparison and identification?
Density is irrelevant in glass comparison and identification.
Density is only used to determine the color of glass.
Density is used to determine the temperature resistance of glass.
Density is used to determine the composition, quality, and type of glass.
How can the presence of tempered glass be identified in a forensic investigation?
Analyze the chemical composition
Examine the fracture pattern
Measure the thickness
Check for any visible scratches
