Wavelength and Frequency

Formulas:

Practice problems:

1. What is the frequency of a photon whose energy is 6.00 x 10^-15 J? Identify the color of this radiation.

2. What is the energy of a photon whose frequency is 2.22 x 10¹⁴ s^-1?

3. What is the wavelength of radiation whose frequency is 5.00 x 10¹² MHz?

Principles/ Rules

• Aufbau Principle: Lower energy levels must be filled before higher ones

• Pauli Exclusion Principle: Electrons in the same orbital must have opposite spins

• Hund’s Rule: One electron must be present before pairing
