Unit 3 Things to Memorize

Question 1

What is the equation for the inverse relationship between frequency and wavelength?

Variables
h = Planck's constant 
v = frequency 
λ = wavelength 
E = energy 
c = speed of light

Answer 1

c = vλ

Question 2

What is the equation for the amount of energy absorbed when the wavelength is given in the problem?

Variables
h = Planck's constant 
v = frequency 
λ = wavelength 
E = energy 
c = speed of light

Answer 2

E = hc/λ

Question 3

What is Planck’s constant?

Answer 3

h = 6.626 * 10^34 J/s

Question 4

What is the speed of light?

Answer 4

c = 2.998 * 10^8 m/s
