Warping of light waves to fit through small opening

Question 20

Refraction

Answer 20

Bending of the path of light waves when in enters another substance

Question 21

Blackbody radiation

Answer 21

Light emitted by a solid object when sufficiently heated

Question 22

Quantum

Answer 22

A unit of fixed amount of energy (quantized energy)

Question 23

Quantized

Answer 23

Occurring in fixed amounts rather than being continuous

Question 24

Bohr Model of Hydrogen Atom

Answer 24

H atoms have a stationary state, they only have fixed energy levels

Question 25

Stationary state

Answer 25

Fixed energy amount present in a H atom, determined by the distance of the electron’s orbit from the nucleus

Question 26

Ground state

Answer 26

The lowest energy state an atom can be at (smallest electron orbit)

Question 27

Layman Series

Answer 27

Series that produce UV light

Question 28

Balmer Series

Answer 28

Series that produces visible light

Question 29

Pascher Series

Answer 29

Series of energy that produces IR light

Question 30

Heisenberg’s Uncertainty Principle

Answer 30

It is not possible to know both the position and momentum of a moving particle simultaneously

Question 31

Quantum-mechanical model of atom

Answer 31

You can’t find exact location of electron, only where it’s likely to be

Question 32

Schrodinger wave equation

Answer 32

solves for the energy states associated with a particular atomic orbital

Question 33

Probability density

Answer 33

Likelihood that the electron of a particular energy is in a particular spot

Question 34

Hund’s Rule

Answer 34

low energy sublevels must be filled before filling higher energy sublevel

Question 35

Pauli’s Exclusion Principle

Answer 35

No orbital can contain more than 2 electrons
