Liquid Crystals

Swarm theory was proposed by .....................

Name the liquid crystals in which the molecules can move sidewise in either direction and rotate along their axes.

• Smectic

• Nematic

• Cholesteric

Smectic Liquid crystal is not affected by magnetic field.

• True

• False

Which liquid crystal is optically active ?

The temperature at which turbid liquid changes to true liquid is called

• Melting point

• Boiling point

• Transition Temperature

Anisotropic behaviour is shown by

• Solids

• Liquids

• Gas

• Liquid Crystal

Name the liquid crystal which shows colour effect in polarised light.

• Smectic liquid crystal

• Nematic liquid crystal

• Cholesteric liquid crystal

The liquid crystal having limited mobility

Name the liquid crystal in which the molecules are arrangement in this manner.
