Which of the following is a dichroic crysral?

A

Quartz

B

Tourmaline

C

Mica

D

Selenite

Text Solution

Verified by Experts

The correct Answer is:
B
Some crystals such as tourmaline and sheets of iodosulphate of quinine have the property of strongly absorbing the light with vibrations perpendicular to a specific direction (called transmission axis) transmitting the light with vibration parallel to it. This selective absorption of light is called dichroism.
