Chapter 6: Electronic Structure of Atoms

Question 1

Frequency

Answer 1

the number of complete waves passing any point per second

Question 2

wavelength

Answer 2

the distance between two adjacent peaks (or two troughs)

Question 3

what is frequency measured in?

Answer 3

hertz (how many cycles per second?)

Question 4

What is the order of waves in order of increasing frequency (energy)?

Answer 4

radio, microwaves, infrared, visible, ultra-violet, x rays, gamma

Question 5

What side of the visible light spectrum has higher energy?

Answer 5

purple

Question 6

what is the formula for calculating wave speed?

Answer 6

c (speed of light) = lambda (wavelength) x u (nu frequency)

Question 7

what does it mean about the frequency with longer wavelengths?

Answer 7

low frequency

Question 8

what does it about the frequency with shorter wavelengths?

Answer 8

high frequency

Question 9

What does the quantum theory say?

Answer 9

energy can be released or absorbed by atoms in discrete chunks

Question 10

what is a quantum?

Answer 10

the smallest amount of energy that can be emitted/absorbed (fixed amount)
