The relationship between distance of the object (u), distance of the image (v) and focal length (f) of the lens is called lens formula or lens equation. This lens formula is applicable to both convex and concave lenses. Note : Points to be remembered while using the lens formula. The value..

Ozone (O 3 ) - Ozone is an allotropic form of oxygen. Its molecular formula is O 3 and molar mass is 48 g mol - 1 . Schonbein (1840) concluded that Van Marums observations in 1785 of a peculiar smell, when an electric discharge was passed through oxygen (or air), was in fact a new gas. He named it ..

Energy - Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign these energy numbers is ..

. These key characters enable the students of taxonomy to easily identify and assign any angiosperm plant to its family. Bentham and Hooker have grouped advanced, seed bearing plants into a major division called Phanerogamia. This division has been divided into three classes namely: 1. Di..

The carbon atoms of the parent chain are numbered as 1, 2, 3..., so as to assign the lowest number to the carbon atom where the multiple bond (double or triple) begins. The position of the multiple bond is indicated by adding the serial number of the first carbon of the multiple bond bef..

A hydrogen electrode in which pressure of hydrogen gas is maintained at 1 atm, and the concentration of H + ions in the solution is 1M is called a standard hydrogen electrode (SHE). As the potential of a standard hydrogen electrode is taken as 0.00 V at all temperatures. This electrode is used as..

Constellation is a group of stars visible within a particular region of the night sky. The stars that appear in the form of closed groups and form recognizable shapes and patterns are known as constellations. There are about 88 different constellations across the whole sky.
