Let us now discuss the basic principles of wireless radio communications. We shall mainly concentrate on the principle of amplitude modulation and demodulation. The simplest scheme of wireless communication would be to convert the speech or music to be transmitted to electric signals usin..

A mixture is a combination of two or more elements or compounds in any proportion so that the components do not lose their identity. Air is an example of a mixture (several gases mix to form air). Mixtures are of two types, homogeneous and heterogeneous. Homogeneous mixtures hav..

Troposphere is the blanket of air in which we live where all the weather is formed. Air is a mixture of 78.1% of nitrogen, 20.9% oxygen, 0.03 - 0.04% carbon dioxide, 0.94% noble gases and water vapour. Air is a mixture for the following reasons: - Air..

Lightning and Lightning Conductors - During thunderstorms, large amount of electrical charge separation takes place in the clouds. As a result, some regions of the cloud have overall positive charge, while others have overall negative charge. When this separation becomes suffici..

The respiratory system starts with the nose that encloses the nasal cavity . The nasal cavity opens outside through the openings called the nostrils . The nasal cavity is divided into two portions by a cartilagenous septum and is lined by fine hairs that filter the dust particles from the ..

Impure Substances - Mixtures Impure substances are commonly called mixtures. A mixture is a material containing two or more elements or compounds that are in close contact and are mixed in any proportion. The constituents of mixtures exhibit their individual properties. These constituents can b..

Gaseous Exchange in the Alveolus of Man The capillaries lining the alveoli have impure blood which has low concentration of oxygen. So, the oxygen from the air easily diffuses into the blood through the thin barrier of the alveolus wall. Similarly since the concentration of carbon di..

If a bottle of perfume is opened in one corner or a room, it spreads in the whole room by diffusion. Experiment 3: A gas jar of bromine and a jar of air are placed, separated by a cover plate. The cover plate is removed so that the two open ends of the jars are in contact. Th..

There are a pair of lungs in the thoracic cavity - the left lung and the right lung. The left lung is slightly smaller (because of the heart which is slightly to the left of the body) and has two lobes and the right lung is bigger with three lobes. They are spongy and elastic organs that are broad ..

Total Internal Reflection - Let us consider a ray of light passing from glass to air, that is from a denser medium to a rarer medium. The figure shows that for a small angle of incidence, major part of the incident light is refracted and a small portion is reflected. The refracted ray ben..
