Element Elements and Compounds Dual Nature of Matter and Radiation Structure of Atom Compounds A compound is a substance composed of two or more elements, chemically combined with one another in a fixed proportion. Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Objectives: Dual Nature of Matter and Radiation. De-Broglie’s Equation.

Mineral Coal and Mineral Oil Petroleum Structure of Atom Dual Nature of Matter and Radiation Wave Nature of Radiation James Clerk Maxwell first formally postulated electromagnetic waves. These were subsequently confirmed by Heinrich Hertz. Maxwell derived a wave form of the electric and magnetic equations, thus uncovering the wave-like nature of electric and magnetic fields, and their symmetry.

Mineral Coal and Mineral Oil Petroleum Structure of Atom Dual Nature of Matter and Radiation Wave Nature of Radiation All objects above the temperature of absolute zero radiate energy to their surrounding environment. This energy, or radiation, is emitted as electromagnetic waves that travel at the speed of light. Many different types of radiation have been identified. Each of these types is defined by its wavelength.

Mineral Coal and Mineral Oil Petroleum Structure of Atom Dual Nature of Matter and Radiation Particle Nature of Radiation Max Planck developed a new theory of black-body radiation that explained the observed spectrum. Planck's theory was based on the idea that black bodies emit light (and other electromagnetic radiation) only as discrete bundles or packets of energy. These packets were called quanta.

Mineral Coal and Mineral Oil Petroleum Structure of Atom Dual Nature of Matter and Radiation De- Broglie proposed that matter, like radiation also exhibits a dual behaviour. Matter and radiation act both as particle and wave.

Mineral Coal and Mineral Oil Petroleum Structure of Atom Dual Nature of Matter and Radiation De-Broglie’s Equation According to the de-Broglie’s duality principle, every object in motion has wave character. The wavelengths of ordinary object are so short that their wave properties cannot be detected. The wavelengths associated with electrons and other subatomic particles with very small mass can be detected experimentally.
