Question
What is mean by the dual nature of matter?
Solution
- Material particles show wave-like nature under certain circumstances. This phenomenon is known as wave-particle duality of matter or the dual nature of matter.
- The wave associated with matter is called matter-wave. The wavelength associated with the matter of mass m moving with velocity v is given by,
`lambda = "h"/"p" = "h"/"mv"`
