EM Calculations

Directions: For each problem write the formula, the formula populated with numbers, and the numeric answer with the proper units. Example:

Find the Speed: v

  1. freq = 300 MHz     λ = 1 m
  2. freq = 428.6 THz     λ = 700 nm
  3. freq = 30 PHz     λ = 10 nm

Find the Wavelength: λ

  1. freq = 630 kHz
  2. freq = 106.1 MHz
  3. freq = 106.5 MHz
  4. freq = 1 GHz

Find the Frequency: f

  1. λ = 5 cm
  2. λ = 5 µm
  3. λ = 50 nm
  4. λ = 50 pm
