Photoelectric effect, Hertz and Lenard’s observations; Einstein’s photoelectric equation; particle nature of light. A Photon of wavelength 4.0 × 10-7 m strikes on metal surface having work function 2.13 eV. The magnetic and the electric fields come at 90° to each other and the combined waves move perpendicular to both electric and magnetic oscillating fields occurring the disturbance. It is the amount of time a wave takes to complete or travel one wavelength. Frequency – The number of waves that pass a given point in one second is called frequency. 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… Light of frequency 1.9 times the threshold frequency is incident on a photosensitive material. The relationship of frequency and wavelength has been shown above in the figure of the electromagnetic spectrum as well. Electromagnetic radiation—light—is a form of energy whose behavior is described by the properties of both waves and particles. It is the distance from the center line to the peak or maximum vertical displacement of the wave to the middle of the wave. The wave associated with the particle is called a matter wave or a de Broglie wave. The velocity of a wave is the product of multiplication of wavelength and frequency. Conversely, under some physical circumstances electromagnetic radiation acts as a wave, and under other physical circumstances, radiation acts as a beam of photons. Earned Point(s): 0 of 0, (0) They are the basis for everything in the Universe. There is no charge on X-ray thus these are not deflected by the electric field and magnetic field. 1.Dual Nature of Radiation Wave theory of electromagnetic radiation explained the phenomenon of interference, diffraction and polarisation.
