5 True/False Questions

1. Simple Harmonic Motion →
   Motion that repeats.

   True        False

2. Amplitude → The distance from equilibrium point to the highest or lowest point of a wave. In mechanical waves it is proportional to the energy of the wave.

   True        False

3. Longitudinal wave → A wave whose medium oscillates parallel to the direction of the waves' energy.

   True        False

4. Diffraction → The bending of a wave due to a change in the medium's properties.

   True        False

5. Compression → A region of high pressure of the medium in a longitudinal wave.

   True        False
