Question

1. What is meant by the term dual nature of matter? How was the dual nature of
moving electrons experimental y verified?​

Answer 1

Answer:

Dual nature of matter was proposed by de Broglie in 1923, it was. ... Wave character of matter has significance only for. microscopic particles. de Broglie wavelength or wavelength of. matter wave can be calculated using the following relation: λ=mvh.

Answer 2

Explanation:

As the name suggests Dual Nature of Matter and Radiation chapter deals with the duality in the nature of matter, namely particle nature and a wave nature. Various experiments by various scientists were done to prove it. For example, light behaves both as a wave and as a particle. If you are observing phenomenon like the interference, diffraction or reflection, you will find that light behaves as a wave. However, if you are looking at phenomena like the photoelectric effect, you will find that light behaves as a particle. You must have heard about solar energy in your earlier classes and how it can be a good alternative to the non-renewable sources of energy. We can use solar energy as a source of electricity using solar panels. The solar panel has solar cells (semiconductors like Si and Ge) and when photons hit the solar cells the electrons get excited and due to their movement electric current is produced. So here we got to know that light constitutes of photons or in other words light contains particles which are a packet of energy.

Dual nature of matter was proposed by de Broglie in 1923, it was. experimentally verified by Davisson and Germer by diffraction. ... de Broglie hypothesis suggested that electron waves were being. diffracted by the target, much as X-rays are diffracted by planes of.
