The Carbon Family
Class 11 Chemistry Chapter 11 The p-Block Elements Carbon family include elements Carbon(C), Silicon (Si), Germanium (Ge), Tin (Sn), Lead(Pd). The general electronic configuration of this family is ns2 np2 that means these elements have valency 4. In nature Carbon is seventeenth most abundant element by mass in earth’s crust. However, carbon is found in […]
What are Semiconductors?
Class 12 Physics Chapter 14 Semiconductor Electronics: Materials, Devices and Simple Circuits Electronic devices are characterised by the ability to control the flow of electron. Such devices are made of semiconductors. To understand what are semiconductors, one must know about conductors and insulators. Material having high conductivity and low resistivity are conductors. However, material with […]
The Story of Photon
Class 12 Physics Chapter 11 Dual Nature of Radiation and Matter In this blog we will speak in detail about interesting behaviour of light. Light has the ability to show wave nature as well as particle nature but how? Let’s start knowing. The phenomenon of photoelectric effect confirmed that light is made of small energy […]
The Concept of Photoelectric Effect
Class 12 Physics Chapter 11 Dual Nature of Radiation and Matter Photoelectric effect occurs when light of frequency greater than threshold frequency fall on metal plate, electrons get emitted from the metal surface. In this blog we will talk minor details of photoelectric effect. Story of Photoelectric Effect Heinrich Hertz, was experimenting on the electromagnetic […]
Chemistry of Alkaline Earth Metals
Class 11 Chemistry Chapter 10 s-block elements Alkaline earth metals are also known as Group II elements. These elements are Beryllium, Magnesium, Calcium, Strontium, Barium and Radium. The name alkaline earth suggest that these metals form alkalies with water and are found in earth’s crust. In this article let’s discuss in detail about alkaline earth […]
Concept of polarization of light
Class 12 Physics Chapter 10 Wave Optics During summers, brightness is unbearable to the eye. When you wear sunglasses, intensity of light gets reduced and eyes feel better. The phenomena behind this is, polarization. In this article, you will get detailed understanding of polarization of light. Polarization of light Light travels in random oscillations of […]
What is Surface Tension in Liquids?
Class 11 Physics Chapter 10 Mechanical Properties of Fluids In day to day life surface tension has various example like floating of water striders on water, fluid in test tube raised at the boundaries, floating of oil on water and many more. Phenomena of Surface tension is well explained by science. In this article, let’s […]
Globalization and Indian Economy
Class 10 Economics Chapter 4 Globalization and Indian Economy Globalization is the rapid integration of countries through foreign trade and foreign investment by multinational cooperation or MNCs. The money that spend on buying asset such as land, buildings, machines and other resources is called investment. When MNCs made this investment in different countries then it […]
Kepler’s Law of Planetary Motion
Class 11 Physics Chapter 8 Gravitation Stories of planetary motion, theories and phenomena always attracted scientist. Johannes Kepler studied planetary motion and formulated his finding in three laws. In this article let’s talk about kepler’s law in which we will discuss in brief about law of orbits, law of areas and law of periods. Kepler’s […]
