Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following best describes a transverse wave?
Particles oscillate parallel to the wave direction.
Particles oscillate perpendicular to the wave direction.
The wave transfers matter, not energy.
It requires a vacuum to propagate.
2. The phenomenon where waves bend around obstacles is called:
Reflection
Refraction
Diffraction
Interference
3. The maximum displacement of a point of a wave from its equilibrium position is called the .
4. The number of complete oscillations a wave makes per unit time is known as its .
