Answer:
Step-by-step explanation:
a) Medium - any substance with a defined set of physical properties that can transmit energy. According to wave, which is a disturbance that travels through a medium and transfer energy from one point to another. The medium here can be water and this water is the one transmitting the wave motion and also energy.
b) disturbance - the displacement of an object from its equilibrium position by the input of energy. Example is a waveform as described in (a) above. The displacement of an object causes the object to leave its initial position with the aid of an input energy called the force.
c) oscillate - to bob back and forth in a regular way about a resting position. The to and fro movement of an object exhibits an oscillatory motion. Example is motion of a simple pendulum.
d) propagate - to transmit from one place to another in succession. Propagating means transmitting energy or force from one point to another in succession i.e repeatedly.
e) equilibrium - the natural or rest position of a particle. When a body is in its position of rest, it is known to be in equilibrium i.e the sum of forces acting on the body is zero
