More about Refraction of Light through a Rectangular Glass_ Proofs of some basic properties and Factors affecting Refraction

  Go straight, Turn Left, Slight Right and straight again. Finally, you have reached! Welcome! Welcome to the World of Light once again!  I do hope you really enjoyed your previous visit into our mindboggling world. Today we are going to dive deeper in to our renowned town of refraction which is one of the main places scientists choose for adventure sports in our World. Strap in and get ready for the roller coaster ride as we go through the peculiar effects of a glass slab and different mediums on light. (If you haven't read the previous blog about the Basics of Refraction of Light and Snell's Law, click on this link !  The Refractive Indices of Light and its relation with the Snell's Law  . I would suggest you to read that , before you move ahead in this blog as we will be referring to few concepts from it.)   In this blog we will understand why:- Q) The   Angle of Incidence always equal to the Angle of Emergence  in a glass slab? Q) The Incident...

Famous or Important Persons in "The Rise Of Nationalism in Europe"

 Same chapter, Different Blog "The Rise of Nationalism in Europe " is a chapter with many layered information, hence like the last blog, we are going to dive deeper into uncovering the indepth knowledge given in this chapter by discussing the important leaders, painter and freedom fighters mentioned. (If you haven't read the previous blog "The Rise of Nationalism In Europe __Important Years and Dates" yet,  Click Here!  ) Okay let's begin 1) Fredrich Sorrieu --.  French Artist who painted a series of four painitings visualising his dream of a world made up of "Democratic and Social Republics". 2) Earnest Renan -- French Philosopher, delivered a lecture at University of Sorbonne outlining his understanding of What makes an Nation.  3) Andreas Rebmann -- Designed the cover of German Almanac at 1798 4) Napolean Bonarpte -- * French Ruler, who established the Napleonic Code of 1804                        ...

The Sense Organs and Chemistry_ Observations of Practical Chemistry and Lab Activities

One of the many things which makes Chemistry fun is Practicals. Wearing lab coats , pouring liquids together in delicate glass ware ,  experiencing an explosion in the back bench because of some careless friend. (Let's hope the last one doesn't happen), but this year most highschoolers had to miss these fun times in the lab due to online schooling. Simulations and Videos are useful but not as engaging as pouring acids and bases with your own hands, and along with missing memorable times with the bunsen burners, we also missed many important concepts related to practicals which might be asked in Boards. In this blog, We will try to bridge few of these gaps experienced by highschoolers because of the missed lab practicals, Helping us answer any activities or practicals related MCQ's in the first term easily. Colours of few common metals and salt solutions :- CuS -- Black in colour  ZnCl -- White in colour  To check the release of gases during a reaction 1) Hydrogen -- Brin...

The Rise of Nationalism In Europe __Important Years and Dates

 The Rise of Nationalism in Europe -- A chapter containing 2 centuries of European History, in 20 pages. Stretching from France to Balkan region, It covers all the major incident which has occured in Europe in the context of Nationalism.  This is a topic of immense importance  both due to its humungous size and the fact that it is the only chapter from History coming  in the 10th Board exams Term.1 MCQ. This blog will hopefully help you remember all the Dates and Years mentioned in the chapter.  (Kindly note that the Years are not in exact chronological order but instead go with the flow of chapter as per NCERT textbook)  So, Let's Start!  1. 1848 - Frederich Sorrieu's Painitings on Democratic and Social Republics ( French Artist)  2. 1882 - Lecture at University of Sorbonne by ERNST RENAN 3. 1789 - French Revolution 4. 1790's - French moved into Belgium, Switzerland and Italy to spread Nationalism 5. 1798 - German Almanac design by ANDREAS RE...

The Refractive Indices of Light and its relation with the Snell's Law

Light is both a particle and wave, it doesn't have mass but still interacts with other matter. These are few of the confused and oxymoronic statments you might be coming across in your Physics textbook.  The thing which makes everything visible is mostly invisible. (No, It's not crazy ... It's Physics😝) Light is an entity , which is responsible for our existence, You literally won't be able to read this blog without this entity of physics. No wonder why physicist  like Einstein and Newton spent majority of their life trying to study this incredible phenomena.      In this blog, we will try  discussing about one of the properties of light out of the thousands discovered throught out human civilisation --- Light through different medium ... Light travels in a straight line,  In the Rectilinear Propoagation of light, we learnt that light travels in a straight line (basically propogates rectilinearly) , hence we get sharp shadows of images, but this is t...

Why is -v/u = Magnification of Spherical Mirror? ____Proof of Magnification formula

Magnification of mirror = Most high schoolers, know this formula byheart. Seeing this formula might take you back to your memories of all the  panic attacks you had just before the board exams trying to remember this formula amongst the various other concepts learnt in the Light - Reflection and Refraction chapter (Yes, been there  😌)   This formula was and is  very important, both for the boards and real life applications of optical physics. So we all know this formula byheart , Which is, we just know that m = -v/u, but do you know why they are equal?  But, first to all those who are wondering What is Magnification!? Magnification is the ratio of the height of the image and height of the object, basically telling us how large or small the image is from the object The common formula this is denoted by is - height of image / height of object  so this is (somehow) related to -v/u ... In this blog we will dive deeper into this "somehow"  First let u...
