Why We're Here

Question 1

1) How does electrons get promoted

2) What level does a electron at 90 nm wavelength promote to

Answer 1

1) Specific wavelength get electrons promoted to specific energy level
2) 4n, Smaller wavelength equates to larger energy

Question 2

Wavelength & Frequency
Which denotes: 
1) Lambda
2) v
3) Why are they inversely proportional

Answer 2

1) Wavelength
2) Frequency
3) Smaller the wavelength the higher the frequency

Question 3

Frequency proportional to energy

Answer 3

As frequency increases so does energy

Question 4

Energy formula

Answer 4

E = h v
(h = Planck's constant

Question 5

Planck’s Constant

Answer 5

6.626 x 10-34 J s

Question 6

Violet wavelengths

1) Long or short
2) High or low energy

Answer 6

1) Short

2( High energy (promotes further away from the nucleus)

Question 7

What is the relationship between absorption and emission spectra?

Answer 7

They’re opposites
