Question

A notebook has lustre while eraser does not.

• A. True
• B. False

Answer 1

The correct option is B False

Lustre:

• Metals have the property to display lustre.
• Lustrous is a property of metals due to which they have shiny surfaces due to the reflection of light from the surface.
• The intensity of the lustre depends upon the amount of light reflected from the surface, which is generally related to the refractive index of the material.

As a notebook and an eraser are non-metal, therefore they do not have lustre.

• Notebooks are made up of paper which is derived from wood pulp and contains Carbon, $\left(\mathrm{C}\right)$ a non-metal.
• Erasers are polymers derived from Carbon as a major raw material that is also non-metal.

Exception: Certain forms of Carbon like graphite and diamond exhibit lustre.

Therefore, the given statement is False.
