Question

  1. A. frequency: medical or industrial application in a medical ultrasound scan
  2. B. frequency: a generic statement that ignores reflected pulses, timing and boundary echoes
  3. C. frequency: a boundary mistake that confuses sound reflection versus electromagnetic imaging
  4. D. frequency: a different Unit 4.6 idea from outside Types of electromagnetic waves

Answer

Application check: radio waves are identified by their low frequency and long wavelength in communication contexts, which distinguishes them from infrared, ultraviolet and gamma radiation. Correct option: frequency: medical or industrial application in a medical ultrasound scan

Explanation

frequency: medical or industrial application in a medical ultrasound scan is correct because Application check: radio waves are identified by their low frequency and long wavelength in communication contexts, which distinguishes them from infrared, ultraviolet and gamma radiation. It stays anchored to the Unit 4.6 learning objective and avoids mixing wave speed, frequency, wavelength, transverse motion or electromagnetic-spectrum order.

Common mistake
