natural hazards observer

Some of these wastes are also classified as hazardous wastes. are those that are potentially dangerous and can cause diseases, fire, etc. The hazardous wastes include toxic wastes. Toxic wastes are those that are poisonous in nature. Hazardous wastes are tho..

Nature of Light - Light is a form of energy and can be transformed into other forms of energy. You would have observed the path of 'a beam of light' inside a room. This beam is nothing but the scattered light produced by the dust particles and this beam of light becomes invisibl..

Light is a form of energy and can be transformed into other forms of energy. You would have observed the path of 'a beam of light' inside a room. This beam is nothing but the scattered light produced by the dust particles and this beam of light becomes invisible if the room is dust free. ..

Aristotle and other medieval thinkers believed that the natural state of bodies is the state of rest. Galileo opposed this concep..

Are Negatively ChargedWhen an electric field is applied in the path of cathode rays, they are deflected towards the positive plate of the electric field, which shows cathode rays are made up of negatively charged particles. The nature of the cathode rays does not depend on the nature..

The state of reversible reaction at which the concentrations of reactants and products do not change with time is called a state of chemical equilibrium. This state can be recognized by the constancy of certain measurable properties such as pressure, density, colour, concentration, etc. At equilibr..

Equilibrium and its Dynamic Nature - The state of reversible reaction at which the concentrations of reactants and products do not change with time is called a state of chemical equilibrium. This state can be recognized by the constancy of certain measurable properties such as pressure, d..

According to wave theory when light falls on a metal surface, energy is continuously distributed over the surface. All the free electrons receive light energy and when the energy received exceeds that of work function, an electron may escape the surface. If we user a low intensity source, it may ta..

Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It was observed that some of the experimental facts..
