Quantum Flashcards
The man from New Zealand who Discovered atomic nucleus
Ernest Rutherford
Who was the first to use a terminology ‘quantum’?
Max Planck
Newton’s 2nd law?
An object of mass m undergoes an acceleration a when acted upon by a force F. In the form of an equation, this reads F = ma
Who discovered that light is a wave?
James Clark Maxwell
Explain F = G x m1 x m2 / r^2
What is F, G, m1, m2 and r^2
F - force
G - Gravity
M1 and M2 - mass of the two objects
r^2 - square distance
Force equals gravity times the two masses divided by square distance (between the two masses)
What does ‘quanta’ mean?
Packets or Discrete
Where did Max Plank work?
Paris
Where is Ernest Rutherford from?
New Zealand
Max Planck
Came up with word ‘quantum’
Where is James Clerk Maxwell from?
Scotland
Ernest Rutherford
Discovered atomic nucleus
Henri Becquerel
Discovered radioactivity in 1896
Who discovered radioactivity?
Henri Becquerel
James Clerk Maxwell from Scotland
Showed that the Light is an electromagnetic wave
Who came up with a new approach to quantum theory?
The job of Nature is to make predictions for quantities that can be compared to experimental result.
German physicist Werner Heisenberg
When was radioactivity discovered?
1896
Who described once a self important official as being ‘like Euclidean point: he has position without magnitude”
Ernest Rutherford
What nationality is Niels Bohr
Danish
Newtons 1st law?
Every object remains in a state of rest or uniform motion in a straight line unless is is acted upon by a force
What happens when electrons jump orbits?
They emit light
When did Isaac Newton published his lows?
5 July 1687
Newton’s equation of gravity?
F = G m1xm2/r^2
Jumping electrons emitting light
Niels Bohr
Who published the first quantum theory of atomic structure and when?
Niels Bohr in 1913
