Question
Quantum effects are not important at the macroscopic level because Planck's constant h is a very small quantitiy.
True
False
According to Heisenberg when the position of an electron is well known its momentum can be fairly well determind.
True
False
The Quantum ideas were introduced in Physics by Max Planck in his studies of:
Uranium radioactivity
Black body radiation
The photoelectric effect
None of the above
Louis de Broglie theoretically proposed that every subatomic particle must show particle-wave dualitiy.
True
False
In Quantum Physics it was discovered that:
light waves never show particle behavior
particles show wave behavior under specific conditions
light presents diffraction when passing near the edge of a body
None of the above
Uranium radioactivity
Black body radiation
The photoelectric effect
None of the above
Explanation / Answer
1.
True
2.
False. It's quite opposite of the statement. If the position is well defined then momentum uncertainty would be very high.
3. Blackbody radiation
4. True
5. Particles show wave behavior under specific conditions.
