Electric and magnetic fields constitute:
Correct answer: A. Electromagnetic wave
- A. Electromagnetic wave
- B. Transverse waves
- C. Longitudinal waves
- D. Stationary Waves
Explanation
Waves that do not require any medium for their propagation are called electromagnetic waves. These waves propagate due to the oscillations of electric and magnetic fields.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
