Wave motion is the motion in which a disturbance travels through a medium transferring energy from one point to another without transfer of matter.
In wave motion, particles of the medium oscillate about their mean positions, but the medium as a whole does not move.
Wave motion is different from motion of particles. Only energy propagates, not the particles themselves.
Q1. Wave motion involves transfer of: A) Matter only B) Energy only C) Both matter and energy D) Neither matter nor energy Answer: B Q2. In wave motion, particles of the medium: A) Move forward permanently B) Remain at rest C) Oscillate about mean position D) Travel with the wave Answer: C Q3. Which of the following is NOT a property of wave motion? A) Transfer of energy B) Transfer of matter C) Oscillation of particles D) Definite wave speed Answer: B Q4. Sound waves travelling in air are an example of: A) Circular motion B) Linear motion C) Wave motion D) Random motion Answer: C Q5. Wave motion is produced due to: A) Translation of particles B) Rotation of particles C) Oscillation of particles D) Motion of medium as a whole Answer: C Q6. In wave motion, the medium: A) Moves with the wave B) Moves partially C) Does not move as a whole D) Moves permanently Answer: C Q7. Water waves on the surface show: A) Motion of water only B) Transfer of water C) Transfer of energy D) No motion Answer: C Q8. Which quantity is transferred in wave motion? A) Mass B) Charge C) Energy D) Volume Answer: C
Propagation of a disturbance that transfers energy without transfer of matter.
Particles oscillate about mean position.
