Hello friends, I hope we all are aware by the term x rays. May be we or one of our friends or relatives have gone through the procedure of x rays. Let us today discuss how x rays were discovered and why x rays are known as x rays?
Dear friends, today we will discuss about the basics of Smith Chart or construction of Smith Chart. Let us understand, what is Smith Chart:
- Smith chart is a graphical method to solve transmission line problems.
- It is a graph between resistance component (R/Z0) (or conductance component, C/Y0) and reactance component (±iX/Z0).
JEE main and NEET entrance exams are two major exams to take admissions in engineering and medical colleges respectively. Let us discuss about them:
When students start their preparation for UPSC, there are several questions pop up in their mind. How to start, where to go, what to read, when to prepare etc. These questions are quite obvious and it’s also normal to have such queries. There are various platforms to guide the beginners.
Science is a systematic approach that collects and builds knowledge. Likewise, they are many scientific discoveries happening in every part of the world. But there are amazing and outstanding discoveries and inventions made in recent times that are incredible. Some are listed below:
The concept of Fermi Level:
In simple term, the Fermi level signifies the probability of occupation of energy levels in conduction band and valence band.
In extrinsic semiconductors, the number of electrons in the conduction band and the number of holes in the valence band are not equal.
You must have seen that astronauts wear spacesuits when they land on moon.
Do you know the reason? The reason is that moon has no atmosphere. Exactly, I should say it has negligible atmosphere. Let us discuss. As the gravitational force of moon is 1/6th on the gravitational force on earth. The escape velocity of gases or air molecules on earth is greater than the moon. Continue reading “Why there is no atmosphere on moon”
The persons who are interested to be updated about the latest science and technology news. There are many online websites which provide information about the current research. These websites provide information through press releases. Continue reading “Where to get information of latest science news”
In my one of earlier articles on Newton’s law, I have discussed about the Newton’s second law. We all are also aware about the Newton’s first law which mainly states that if an object is at rest will remain at rest and if it is in uniform motion will remain in uniform motion until and unless some external force is applied on it. Continue reading “Why Newton’s second law is the real law of motion”
Do you want to be a scientist or an engineer? If you are opting for science stream and wondering what will you do after completing your plus two class. In India, most of the students of the non medical stream, after plus two pursue engineering because there is no shortage of engineering colleges in India or outside India. They may not get admission in the best or next best college but surely they will get admission in an engineering college. As we are discussing about science and engineering, let us first discuss the meaning of these two: Continue reading “Do you want to be scientist or engineer”
