If a beam of light travels through a piece of glass at 120,000 miles per second, the refractive index of the glass is approximately

• 0.5

• 1

• 1.5

• 2

The bright halo of light seen around a transparent solid immersed in a liquid with a different refractive index is called

• concentric fracture

• radial fracture

• becke line

• conchoidal line

It is possible to determine the direction of force that caused glass to break by looking at

• conchoidal lines

• becke lines

• the density of the glass

• the refractive index

It is possible to determine the sequence of impacts in a piece of glass by looking at

• the concentric fractures

• the radial fractures

• the becke line

• the refractive index

Why does a transparent object disappear when immersed in a liquid with the same refractive index?

• the speed of light changes as it passes through each medium

• the becke line can be seen

• the speed of light is the same as it passes through each medium

• the color of the object changes

How is glass similar to a liquid?

• it does not have an ordered structure

• it is brittle

• it has a high melting point

Which component is primarily responsible for the transparency of glass?

• Silica

• Lime

• Soda

• Metal oxides
