give any four characteristics of wave motion
Answers
Explanation:
♤■wave is a disturbance travelling through the medium
♤■only energy is transferred in a wave motion
♤■ energy transfer take place with the constant speed if medium properties are homogeneous
♤■wave velocity is constant throughout the medium by a velocity of particle is different at different positions
♤■there is a continuous phase difference amongst the successive particles of the medium
♤■wave motion is possible in a medium which processor the property of elasticity and inertia
Answer:
★ Wave motion is due to the repartee periodic motion of the particles of the medium about their mean position.
★ It is necessary that the medium should possess elasticity and inertia.
★ All the particles of the medium do not receive the disturbance at the same instant (i.e) each particle begins to vibrate a little later than its predecessor.
★ During the propagation of wave motion, there is transfer of energy from one particle to another without any actual transfer of the particles of the medium.
★ The waves undergo reflection, refraction, diffraction and interference.
