Question

provide some examples of matter waves which describes quantum physics theory? give a proper answer...
it is so so so urgent please answer it fast...

Answer 1

Matter waves are a central part of the theory of quantum mechanics, being an example of wave–particle duality. All matter can exhibit wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave. The concept that matter behaves like a wave, proposed by Louis de Broglie in 1924, is also referred to as the de Broglie hypothesis (/dəˈbrɔɪ/).[1] Matter waves are referred to as de Broglie waves.

The de Broglie wavelength is the wavelength, λ, associated with a massive particle and is related to its momentum, p, through the Planck constant, h:

{\displaystyle \lambda ={\frac {h}{p}}.}

Wave-like behavior of matter was first experimentally demonstrated by George Paget Thomson's thin metal diffraction experiment,[2] and independently in the Davisson–Germer experiment both using electrons, and it has also been confirmed for other elementary particles, neutral atoms and even molecules. The wave-like behavior of matter is crucial to the modern theory of atomic structure and particle physics.
