Wavelength and frequency of a wave are inversely proportional. ≫ de Broglie wavelength : The de Broglie wavelength associated with a moving particle is related to its momentum as de Broglie wavelength, where m is the mass of the particle, v is the velocity of the particle, p is the momentum of the particle. Candidates who are ambitious to qualify the CBSE Class 11 Chemistry with good score can check this article for Notes. Electromagnetic waves show dual nature. Thermodynamics As we know –. Different regions of the electromagnetic spectrum are identified by various names. Other characteristics of a wave are amplitude and period. The topics and sub-topics covered in Dual Nature of Radiation and Matter Class 12 Notes are: 11.1 Introduction. 5. Particle Nature of Electromagnetic Radiation. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. Wavelength – The distance of one full cycle of the oscillation is called wavelength or the distance between two adjacent crests or troughs of a wave is called the wavelength. These quick notes are prepared strictly according to the latest CBSE syllabus for Class 11. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. Radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays and gamma rays are all electromagnetic radiations. Moreover, the chapter covers various topics that explain a lot of things about the properties, effects, emission, and nature of radiation and matter. Results are being recorded. Radiation has dual nature, wave, and particle. Planck explain the distribution of intensity of the radiation from black body as a function of frequency or wavelength at different temperatures.

The energy of the photon is related to the wavelength of electromagnetic radiation according to: Planck's constant. Electromagnetic radiation can be defined as a form of energy that is produced by the movement of electrically charged particles traveling through a matter or vacuum or by oscillating magnetic and electric disturbance. Electromagnetic wave theory This theory was put forward by James clark Maxwell in 1864.. Planck's constant is a physical constant named after Max Planck. Hz is of visible light. diffraction etc., but it could not explain the following. Besides, photons assume an essential role in the electromagnetic propagation of energy.
