Meaning of renewable energy:
The term renewable energy is very popular now a days. Due to depletion of other resources of energy, there is need of other sources of energy. Let us first discuss the meaning of renewable. As the name suggests the term Renewable consists of two terms. One is “Renew” means “which can be used again and again” and second term is “able”. Thus renewable means which is able to be used again and again. Continue reading “Meaning of Renewable energy and 6 major types of renewable energy”
Last time, we have discussed about the origin of name of x rays that is why x rays are known as x rays.
Today, we will discuss how x rays are produced? It is proved that whenever fast moving electrons strike a target material of high atomic number and high melting point x rays are produced. But what happen after the collision of electrons? Why and how x rays are produced then? Let us discuss it:

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.

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).

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”
