Dear friends, last time I have discussed about the origin of x rays.
Let us today discuss about the two types of x rays on the basis of their energy:
soft x rays and hard x rays.

Why X rays are known as X rays
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?
INTRODUCTION TO SMITH CHART
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).

10 Interesting Science Discoveries
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:
Fermi level in semiconductors
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.
Why there is no atmosphere on moon
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”

Why Newton’s second law is the real law of motion
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.
