Which of the following is a dichroic crystal?

Options

  1. AQuartz
  2. BTourmaline
  3. CMica
  4. DSelenite

Correct answer

B. Tourmaline

Step-by-step solution

Materials which have different absorption for perpendicular incident plane for light are called dichoric material crystal. Tourmaline is one example of such type of crystal.
