Question

The matter waves are

• A. Electromagnetic waves
• B. Sound waves
• C. de-Broglie waves
• D. Both 1 and 2

Answer 1

Answer: (C)

de-Broglie waves

It is a wave associated with particles revolving in an atom around nucleus. De-Broglie named these waves as matter waves or De Broglie's waves. its wavelength is calculated from wavelength $\lambda =h/mv$,

where, h is plank constant.

This theory mainly conveys the wave nature of light having energy given by plank $E=hv$. ($v$ is frequency of radiation).

These waves do not require any material medium for it propagation. it is coming in mainly non relativistic theory.
