WAVE NATURE OF PARTICLES

Question 1

Which experiment shows that particles can behave like waves?

Answer 1

Double-slit experiment with electrons (interference pattern will be exhibited)

Question 2

What is the result of Bohr’s condition for angular momentum?

Answer 2

Electron wavelength must fit in circle

Question 3

What is the uncertainty principle?

Answer 3

A fundamental uncertainty in a moving particle. Position and velocity cannot be known simultaneously as a detectors interaction with a particle would change its state of motion and momentum.
(Physical knowledge is not in principle absolute and it is bound by the uncertainty principle)

Question 4

Who dervied a relation for the uncertainty principle?

Answer 4

Werner Heisenberg

Question 5

What is the Schrodinger equation and what does it do?

Answer 5

A differential equation that describes quantum systems 3 dimensional wave function.

Schrodinger equation can calculate wave function of a system. The square of the wave function is a probability of an electron existing in a particular location.

We have time dependant and time-independent Schrodinger equation.
