Chapter 8

Question 1

What is Schrodinger’s cat

Answer 1

A thought experiment that explains the dual nature of the electron. An imaginary cat is in steel chamber that contains radioactive atoms. When an energetic particle is emitted by one of the atoms, a flask breaks with breaks with hydrocyanic acid. If the flask breaks the cat dies. If the flask breaks the cat dies. If the steel chamber closed its unobserved, which makes the radioactive particle in a state that is both emitted and not emitted. This makes the cat dead or not undead. When chamber is opened , the act of observation forces the entire system into one state or another. The cat will be observed to be dead or alive

Question 2

wave particle duality of light

Answer 2

some characteristics of light can be thought of as a wave and others as a particles

Question 3

Light is what type of radiation?

Answer 3

EM

Question 4

Magnetic field

Answer 4

region of space where a magnetic particle experiences a force

Question 5

Electric field

Answer 5

region in space where an electrically charged particle experiences a force

Question 6

What does this diagram represent?

Answer 6

Em radiation is a wave of osciallting electric and magnetic fields that are perpandicular to eachother moving through spcae

Question 7

How fast are waves in a vacuum?

Answer 7

They move at the speed of light

Question 8

Why is there a delay when hearing/seeing lightning and thunder?

Answer 8

speed of light is faster than the speed of sound.

Question 9

What characterizes waves?

Answer 9

amplitude and wavelength

Question 10

What is frequency?

Answer 10

Number of wave crests that pass through a staionary point

Question 11

What are the two units for frequency?

Answer 11

Hz and s^-1

Question 12

Equation that shows relationship between speed of light, wavelength, and frequency

Answer 12

c =lamda*v

Question 13

what is frequency

Answer 13

number of wavelengths of that wave that pass through a fixed point in one unit time (usually second)

Question 14

What is diffraction?

Answer 14

spreading of waves around obstacles

Question 15

What is the photoelectric effect?

Answer 15

minimum frequency of light or threshold frequency that is reqiured for emission of electron

Question 16

How does light photon interact with single electron to lose energy?

Answer 16

1-releasing electron from binding energy

2-giving the rest as KE to emitted electron

Question 17

What is Eq that goes with photoelectric effect?

Answer 17

KE = hv-I

• I is the binding energy of elecron on surface
• think of energy of photon-energy of electron

Question 18

De-Brogile wavelength equation

Answer 18

lambda = h/mv

Question 19

What is the uncertainty principle?

Answer 19

impossible to know the momentum and location of electron simulatneously. if you know location more, you know less about momentum, vice versa

Question 20

what is n

Answer 20

principle quantum number

Question 21

what is l

Answer 21

anguluar momentum quantum number (shape)

Question 22

what is m_l

Answer 22

magnetic quantum number (orientation)

Question 23

how do you find value of l?

Answer 23

l <= n-1

Question 24

How do you find m_l

Answer 24

range of -l to l

Question 25

What is the Bohr model?

Answer 25

electrons move around nucleus in circular orbit

Question 26

When does electron emit energy as photon

Answer 26

going from high energy level to low energy level

Question 27

when does electron absorb energy?

Answer 27

low energy level to high energy level

Question 28

what is the final state of lyman series?

Answer 28

1

Question 29

what is the final state of Balmer series?

Answer 29

2

Question 30

what is the final state of paschen series?

Answer 30
