Concept:Wave motion is the transfer of energy through vibrations, without the bulk movement of the medium from one place to another.
Explanation:I. Vibration produces waves: Correct. Oscillating particles or fields generate wave motion.
II. Waves transmit energy along the medium: Correct. Energy is carried from the source to neighbouring points.
III. The medium does not travel with the wave: Correct. Particles vibrate about fixed positions, but the wave disturbance moves forward.
IV. Waves do not require any medium for transmission: Incorrect. Mechanical waves, such as sound, require a material medium.
Only electromagnetic waves can travel through a vacuum.
Therefore, statements I, II and III are correct.
Answer:D. I, II and III only.
