This Young’s interference experiment showed that lights (waves) passing through two slits (double-slit) add together or cancel each other and then interference fringes appear. This phenomenon cannot be explained unless light is considered as a wave.
Q. What is dual wave particle nature of light?
In physics and chemistry, wave-particle duality holds that light and matter exhibit properties of both waves and of particles. The idea of duality is rooted in a debate over the nature of light and matter dating back to the 1600s, when competing theories of light were proposed by Christiaan Huygens and Isaac Newton.

Q. What is dual nature of light?
Light has a dual nature. 1.Sometimes it behaves like a particle (called a photon), which explains how light travels in straight lines. 2. Sometimes it behaves like a wave, which explains how light bends (or diffracts) around an object.
Q. Who proposed the dual nature of light to all forms of matter?
de Broglie
Q. How was the dual nature of an electron verified?
Davisson Germer fires an electron beam on the metal surface. In this experiment, they got diffraction patterns of the electrons beam which is the property of the wave. By this experiment, they confirmed that the matter particle such as electrons also has wave-like nature.
Q. What is dual nature of radiation?
Dual Behaviour of Electromagnetic Radiation The photoelectric effect could be explained considering that radiations consist of small packets of energy called quanta. On the other hand, radiations exhibit a phenomenon of interference and diffraction which indicated that they possess wave nature.
Q. Who proposed dual nature of radiation?
Albert Einstein
Q. What are the nature of radiation?
The only difference between the various types of electromagnetic radiation is the amount of energy found in the photons. Electromagnetic radiation travels in a straight line at the speed of light (3 x 108 m/s). Light waves, radio waves, microwaves, X-rays and Gamma rays are some examples of electromagnetic radiation.
Q. Why are de Broglie waves not electromagnetic in nature?
De Broglie waves or matter waves are different from electromagnetic waves. de Broglie waves do not exist in the vacuum like electromagnetic waves. de Broglie waves are the waves that are possessed by every particle due to its dual behaviour. Electromagnetic waves are emitted by a source.
