Definitions
The law that describes how light bends between two media
What is Snell’s Law?
Fractures that radiate outward from the point of impact
What are radial fractures?
Glass made with lead oxide that gives a sparkling appearance
What is (lead) crystal glass
What happens to light when it enters a denser medium
What is slowing down and bending toward the normal?
Circular fractures that form around the point of impact
What are concentric fractures?
A method where glass disappears in a liquid of the same RI
What is the submersion method?
What happens to light when it enters a less dense medium
What is speeding up and bending away from the normal?
The side of glass where radial fractures form
What is the side opposite the impact?
Heat-resistant glass used in labs and kitchens
What is borosilicate glass?
a halo-like ring that appears under a microscope when the glass and liquid have different refractive indexes
What is a Becke line?
If n₁ sinθ₁ = n₂ sinθ₂, this is being applied
What is Snell's Law?
Fracture pattern caused by heat, not impact
What are wavy fractures (heat fractures)?
Glass made of layers designed to resist bullets
What is bulletproof glass?
Glass fragments large enough to be physically fit together
What is physical matching (or fracture matching)?
The refractive index of a vacuum
What is 1?
The hole that is larger when a bullet passes through glass
What is the exit hole?
