In the photoelectric effect, electrons are emitted from matter (metals and non-metallic solids, liquids or gases) as a consequence of their absorption of energy from electromagnetic radiation of very short wavelength and high frequency, such as ultraviolet radiation.

Asking about the nature of matter is unanswerable and uninformative, and ultimately a question of philosophy the problem of physics is to develop methods that allow us to predict the outcome of experiments, to the best of our ability.

This dualism to the nature of light is best demonstrated by the photoelectric effect, where a weak uv light produces a current flow (releases electrons) but a strong red light does not release electrons no matter how intense the red light. The dual nature of light has been extended to a similar duality in matter as well electrons and atoms were originally considered as corpuscles in 1929 prince louis-victor de broglie was awarded the nobel prize for physics for his discovery of the wave nature of electrons. Ncert solutions for class 12 physics chapter 11 - dual nature of radiation and matter is very important when it comes to class 12 physics examination the class 12 ncert solutions for physics chapter 11 is provided here to help 12th standard students to prepare for the subject more efficiently. 387 dual nature of radiation and matter particles they were found to travel with speeds ranging from about 01 to 02 times the speed of light (3 ×10 8 m/s)the presently accepted value.

This dual nature is a property of all forms of radiation and matter and is comprehensively described by the theory of quantum mechanics though it was immediately suspected, following röntgen's discovery, that x-rays were a form of electromagnetic radiation, this proved very difficult to establish.

Dual nature of radiation and matter 69 (a) no electrons will be emitted as only photons can emit electrons (b) electrons can be emitted but all with an energy, e 0. Note : a harmonic wave has a definite wavelength so uncertainty in its wavelength ar = 0 and hence uncertainty in its momentum ap = 0 , as per de broglie's equation. Dual nature is a universal character of our life in this universe the discovery of higgs boson (god particle) on 4th july 2012 has revealed a unique relationship between radiation and matter.

Assume that the de-broglie wave associated with an electron can form a standing wave between the atoms arranged in a one dimensional array with nodes on each of the atomic site. The energy required to liberate an electron from metal surface may arise from various source such as heat, light, electric field etc depending on the nature of source of energy, the following methods are possible.

Subatomic matter is generally quantized in nearly all of its properties wave-particle duality the theory that electromagnetic radiation may be treated as either a particle (photon) or an electromagnetic wave. Natures of either matter or radiation complement each other it is not possibile to demonstrate the exclusive wave or particle nature of either matter or radiation. Like blackbody radiation, this was at odds with a theory invoking continuous transfer of energy between radiation and matter however, it can still be explained using a fully classical description of light, as long as matter is quantum mechanical in nature.
