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 .
Ans: Uses of Polaroids:
1) Polaroids are used in motor car head lights to remove head light glare.
2) Used in three dimensional movie cameras.
3) They are used to produce and analyse polarised light.
4) They are used as filter in photography.
5)They are used in window of aeroplanes to control amount of light.
6) Used in polarising sunglasses (goggles) to protect the eyes from glare of sunlight.
7) They are used to improve colour contrast in old oil paintings.
8) They are used in calculators, watches, monitors of laptops which have LCD screens.

Ans:
A) Plane polarised light: The light waves in which vibrations of the electric field vectors are confined only to one plane are called polarised light.
B) Plane of vibration: The plane in which the vibrations of polarised light take place is called as plane of vibration.
C) Plane of polarisation: The plane perpendicular to the plane of vibration in which there are no vibrations of polarised light is called as plane of polarisation.

Hello guys, in this article I am going to tell you about few and simple tricks and tips on how you can easily activate your window 10 pro free easily.
1) First of all, in your PC/ Laptop you have to go in search box option and type CMD, then you have to open CMD as an administrator and open.
2) In CMD type this code : i) slmgr.vbs /ipk W269N-WFGWX-YVC98B-4J6C9-T83GX then press Enter button.
3) Second code : ii) slmgr.vbs /skms kms.teevee.asia then press Enter button.
4) And last third code : iii) slmgr.vbs /ato then press Enter button.
And now your window 10 pro is successfully activated.
But in some cases, you will find your window 10 pro is not activated by this code, so it means that some files or folder corrupted in your PC/ Laptop.
So that's why your window 10 pro is not activated.
So in that case : 1) First you have to go in setting and in setting you will find update and security option and then you have to go in Recovery option, so in the Recovery option you have to select Reset option and then you have to Reset your PC/ Laptop Completely.
When you click on Reset option then it will show two option i) Keep files and folders ii) Remove files and folder everything so you go in Remove files and Folder.
After completing of Resetting of Pc/ Laptop then you have to update your window 10 pro and then uses above Code in CMD.
It will 💯 fix your issues !!!

Solution:-
t = 20 second.
u = 72 km/hr = 72×1000 / 3600
u = 20 m/s
v = 36 km/hr = 36×1000 / 3600
v = 10m/s
a = v - u / t
= 10 - 20 / 20
= -10 / 20
a = - 0. 5 m/s2
v2 = u2 + 2as
S = v2 - u2 / 2a
= (10)2 - (20)2 / (2 ) × (- 0.5)
= 100 - 400 / -1
= -300 / -1
S = 300 m
∴ The length of the tunnel is 300m.

1) Optical fiber connectors are used to join optical fiber where a connect /disconnect capability is required.
2) Optical fiber connectors are used in telephone exchange for customer premises wiring and in outside plant applications to connect equipment and fiber-optical cables.
3) Outside plant application may require connectors be located underground or on outdoors walls or utility poles.

1) PIN photodiode does not have a high intensity electric field region.
2) sensitivity is very low in PIN photodiode.
1) Avalanche photodetector is a high-intensity electric field region.
2) sensitivity is very high in Avalanche photodetector.
