The dual behaviour of matter was proposed by the French physicist, de-Brogile. State the dual behaviour of matter.

The dual behaviour of matter was proposed by the French physicist , de Broglie. a) State the dual behaviour of matter.

The dual behaviour of matter was proposed by the French physicist , de Broglie. b) A moving electron has a de Broglie wavelength of 7 xx10^ (-7) m. Calculate its kinetic energy. (Plank's constant, = 6.626 xx 10^(-34) Js),( Mass of an electron = 9.1 xx 10^(-31) kg.)

Dual behaviour of matter proposed by de Broglie led to the discovery of electron microscope oftenused for the highly magnified images of biological molecules and othér type of material. If the velocity of the electron in this microscope is '1.6 xx 10^6 ms^(-1)', calculate de Broglie wavelength associated with this electron.
