Chapter 5 Properties of matter and glass

Front

What is the Becke line?

Back

A bright halo observed near the border of a particle immersed in a liquid of a different refractive index.

Front

What does the refractive index measure?

Back

The speed of light in a vacuum compared to its speed in any given substance.

Front

Define refraction.

Back

The bending of light waves due to a change in velocity.

Front

What is an intensive property of matter?

Back

A property that does not depend on the amount of substance, such as density or refractive index.

Front

Which of the following is NOT an intensive property?

Back

Weight.

Front

What type of glass is commonly used in windshields?

Back

Laminated glass.

Front

What is the definition of density?

Back

Mass per unit volume of a substance.

Front

Explain the term 'birefringence'.

Back

The optical property of a material that has a different refractive index in different directions.

Front

What is the significance of the refractive index in optics?

Back

It determines how much light bends when entering a material.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.
