To represent electromagnetic radiation, various kinds of units are used. Find the energy of photon ? Davisson-Germer experiment (experimental details should be omitted; only conclusion should be explained). Electromagnetic waves show dual nature. Amplitude is represented in the above figure. v = frequency of emitted radiation. Conversely, under some physical circumstances electromagnetic radiation acts as a wave, and under other physical circumstances, radiation acts as a beam of photons. These fields are transmitted in the forms of waves called electromagnetic waves or electromagnetic radiation.

If you are looking for solutions of NCERT Textbook problems based on this topic, then log on to Vedantu website or download Vedantu Learning App. As you can see in the above figure of the electromagnetic spectrum that as the wavelength of a radiation increases its frequency decreases. Different regions of the electromagnetic spectrum are identified by various names. Planck's Quantum Theory ,Structure of Atom - Get topics notes, Online test, Video lectures, Doubts and Solutions for CBSE Class 11-science on TopperLearning. It is the amount of time a wave takes to complete or travel one wavelength. Photoelectric effect. The minimum energy needed by an electron to come out from a metal surface is known as “work function” of the metal. The wavelength of the wave associated with any material particle was calculated as: In case of photon, if it is assumed to have a wave character, its energy is given by E = hν where ν is the frequency of the wave and h is Pla… X-ray affects the photographic plate. Other characteristics of a wave are amplitude and period. Properties of Cathode Rays (i) Cathode rays are not electromagnetic rays. 02.25 Emission and Absorption Spectra 2.25 Emission and Absorption Spectra. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. Electromagnetic waves do not require any medium. 11.3.2 Hallwachs’ and Lenard’s observations.
