In transverse waves the particles of the medium vibrate:
Correct answer: B. Perpendicular to the direction of wave motion
- A. Along the direction of the motion
- B. Perpendicular to the direction of wave motion
- C. Opposite to the direction of motion of the wave
- D. Repeat themselves over time
Explanation
In transverse waves particles oscillate perpendicular to propagation direction (e.g., string waves, EM 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.
