Matter waves are – (1) de Broglie waves (2) Electromagnetic waves (3) Transverse waves (4) Longitudinal waves

1 Answer

Answer :

(1) de Broglie waves Explanation: In mechanics, matter waves or de Broglie waves reflects the wave-particle duality of matter. The de Broglie relations show that the wavelength is inversely proportional to the momentum of a particle and is also called de Broglie wavelength.
