Failures Of Classical Mechanics Flashcards

1
Q

What is the photoelectric effect?

A

The minimum photo energy is needed to eject electrons. Below this nothing happens, above this ejected electrons have kinetic energy.

Q

What is the H emission?

A

Hydrogen electrons are emitted at all wavelengths. This is because hydrogen electrons are excited.

Q

What is the photoelectric effect?

A

Because electrons are ejected at all wavelengths. The photoelectric effect is a phenomenon in which all electrons are being ejected at all solid surfaces.

Q

How come the classical fail?

A

They all fail because discrete energies produce quantum results.

Q

What does the classical mechanics state?

A

Due to the intensity of light all “hv” energy eject electrons (fails).

Q

What is wave particle duality of matter and light?

A

Tiny things like light and electrons act like waves (spreading out) and particles.
