What is soda lime glass?
100
calculated by dividing the mass of a substance by its volume
What is density?
100
A beam of light travels in air and then passes through a piece of glass. As the light passes from the air into the piece of glass, the light ray is bent.

The line of fracture that extend outward from the point of impact on a piece of glass
What is radial fracture?
300
a type of glass formed by volcanoes
What is obsidian?
300
used in automobile windows and plate glass windows in stores
What is tempered glass?
300
law to describes the behavior of light as it travels form one medium into a different medium
What is Snell's law?
300
Light strikes crown glass at an angle of 30 degrees. RI= 1.523. Find the angle of refraction.
What is 19.2 degrees?
300
wavy fracture lines that tend to break toward the region of higher temperature.
What is breakage of glass from a fire.
400
the change in the direction of light as it speeds up or slows down when moving from one medium into another
What is refraction?
400
the chemical additive gives the glass a higher refractive index causing the light to bend mores resulting in the sparkle of crystal glassware
What is leaded glass?
400
a halo-like ring that appears under a microscope when the glass and liquid have different refractive indexes

500
a line perpendicular to the surface where the two different mediums meet.
What is the normal?
500

What is tinted glass?
500
when broken pieces of glass are large enough to manipulate together
What is fracture match?
500
The RI for glass is 1.50 and the angle of refraction is 15 degrees for a ray of light traveling from air. Find the angle of incidence
