Explanation / Answer

Part b: option a,b and c are correct

a) They transfer energy

b) They have an amplitude,wavelength and frequency

c) They are created by particle that are distributed from their equilibrium position.

These are the basic characteristics of wave. some of characteristics are as below: Characteristics of Waves Three characteristics of waves can be measured: amplitude, wave-. length and frequency. Longitudinal and transverse waves Waves transfer energy from one place to another but do not transfer any matter. Waves can be produced in ropes and springs and along the surface of water. All these waves can be reflected, they bounce off surfaces. The waves which travel across the surface of water can also be refracted. As the waves cross the boundary between two different depths of water they change speed. This causes a change in their direction (refraction), unless the direction of travel of the waves is along a normal, i.e. at right angles to the boundary.
