  3. Row 1, Col 1 What is refraction? Bending of light waves caused by a change in speed as it passes between two mediums

  4. 1,2 What is density? A property of matter describing The amount of matter in a given volume.

  5. 1,3 What is sand (SiO2)? The major component of glass.

  6. 1,4 What are density and refractive index? Types of glass can be identified by measuring these two physical properties.

  7. 2,1 What is the speed of light? the speed of light waves in a vacuum

  8. 2,2 What is refractive index? A property of matter represented By the ratio of the speed of light In a vacuum to the speed of light In a given medium

  9. 2,3 What are metal oxides? Sodium carbonate and these substances are added to sand to make glass.

  10. 2,4 What is the direction of impact on a glass surface? The 3R rule is used to determine this.

  11. 3,1 What are frequency and wavelength? Types of electromagnetic radiation are distinguished by these two characteristics

  12. 3,2 What is water displacement? The volume of an irregularly shaped object can be measured by this method.

  13. 3,3 What is laminated glass? Type of glass used in automobile windshields.

  14. 3,4 What are radial fractures? Fractures on glass that extend outward from the point of impact like spokes on a wheel.

  15. 4,1 What is the Becke Line? a halo of light on the outside or inside border of a glass sample immersed in a transparent liquid.

  16. 4,2 What is a physical property? A property of a substance which can be observed without changing the identity of the substance.

  17. 4,3 What are Borosilicates? Type of glass with exceptional Heat resistance used for Cookware and laboratory glassware.

  18. 4,4 What is tempered glass? The sequence of impact for Multiple impacts on a glass Surface cannot be determined For this type of glass.

  19. 5,1 What is density? the refractive index of a substance depends upon its temperature and this phyical property

  20. 5,2 What are grams per mL? Units of density.

  21. 5,3 What is molten tin? Float glass, used in windows, has a smooth surface formed as the glass is cooled in this type of bath.

  22. 5,4 What is the sequence of impact? The fact that a glass fracture line always terminates at an existing fracture line is useful for determining this.
