The wave equation may be written in symbols as v = fλ where f stands for frequency, v stands for velocity and λ stands for wavelength. If a wave has a speed of 3 × 108 m/s what is its frequency and wavelength?

  1. f = 10 000 Hz and λ = 0.0003 m.
  2. f = 5 × 1014 Hz and λ = 6 × 10−7 m.
  3. f = 6 × 104 Hz and λ = 0.5 × 10−4 m.
  4. f = 2 MHz and λ = 3 × 105 m.
