Questions and Answers

What is the primary purpose of using the formula v = f λ in wave physics?

  • To explain the behavior of longitudinal waves
  • To describe the properties of transverse waves
  • To calculate the speed of light in a vacuum
  • To determine the frequency of a wave given its wavelength and speed (correct)

    • What is the main difference between ionising and non-ionising radiation?

  • Ionising radiation has a higher frequency than non-ionising radiation
  • Ionising radiation has enough energy to remove electrons from atoms, while non-ionising radiation does not (correct)
  • Ionising radiation has a shorter wavelength than non-ionising radiation
  • Ionising radiation is only found in the visible spectrum, while non-ionising radiation is found in the electromagnetic spectrum
