smallest particle in nature

Particle Nature of Light - 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 surfac..

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..

At present we know that the atom is the smallest particle of an element, which may or may not have independent existence. It is made up of sub-atomic particles like electrons, protons and neutrons. Atoms of one type of element differ from those of the other due to diff..

Summary - Matter is anything that occupies space and has mass. Element is a pure substance, which can neither be decomposed nor built from simpler substances by any physical or chemical means. It contains only one kind of atom. Broadly speaking, elements can be divided into metals, non-metals and m..

The sum of the three consecutive natural numbers lies between 66 and 81. Find the smallest and largest possible numbers. => Smallest: 22 and Largest: 26 or Smallest: 22 and Largest: 25 or Smallest: 65 and Largest: 80 or Smallest: 23 and La..

Intensive investigation by scientists over the years led to the development of a mental model known as 'dynamic particle model..

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 ..

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. Beam of light becomes invisible if the room is dust free. Thus li..

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..
