Ans:
1) The property by which some doubly refracting crystals absorb the ordinary rays (O-rays) completely and extraordinary rays whole direction is parallel to the optic axis passing through the crystal, is called dichroism.
2) The crystal possessing dichroism property is called dichroic crystal.
3) Dichroism substance produces linearly polarised light
4) This property of substance is used to construct a Polaroid.
Example: Tourmaline crystal.
Hello friends my name is Rajakumar Dayashankar Gupta . Here I am started to write blog on name scientechplus . I am started to writing this blog post on science , technology and engineering since 2020 . I completing my ssc , than after I go for stream in science field , than after completing my 12th science than later I realize my self , I am interested in electronics fields , so I start learning in diploma electronics engineering . My journey is quite interesting to choosing right decision of my aim . And I want to explain the concept in simple and precise way . I every time want to learn something new , it means that something new from open minded from our environment . To learn something new from our expectation . It quite special and very interested to hear that , when we imagine or think we go to learn something very uniqueness our eyes fill with glow , that moment is such a very great pleasurable moment we feel isn't it ? . And I want to share the information , facts , knowledge related to all science , technology and engineering in detail , simple and precise way .
