What is the relationship between wavelength and frequency?

  1. Wavelength gets longer as frequency increases
  2. Wavelength gets shorter as frequency increasesПравильный ответ
  3. Wavelength is constant at all frequencies
  4. Wavelength and frequency increase as path length increases

Объяснение

Wavelength and frequency are inversely related through the fixed propagation velocity of electromagnetic waves in free space, so raising the frequency shortens the wavelength. That is why 2 metres is a much higher frequency band than 40 metres.
