#1  The Correct Answer is D

<span>D) The Distance Traveled by The Wave During One Full Cycle.

Ex. frequency, wavelength, amplitude and wave speed. Amplitude is measured in metres (m). The greater the amplitude of a wave then the more energy it is carrying. The wavelength, λ, of a wave is the distance from any point on one wave to the same point on the next wave along. 

(The symbol is a Greek letter, 'lambda'.)
  

 #2  The Correct Answer is B

</span><span>B) Police Siren 

Ex.
Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist. </span>
