Read each question carefully and answer to the best of your ability. Show all your work where applicable.
1. What phenomenon occurs when two or more waves overlap while propagating through the same medium?
Reflection
Refraction
Superposition
Diffraction
2. When two waves meet crest-to-crest, what type of interference occurs?
Destructive interference
Constructive interference
Standing wave
Polarization
3. The principle of states that when two or more waves overlap, the resultant displacement at any point and at any instant is the vector sum of the displacements due to the individual waves at that point and instant.
4. When a crest meets a trough of equal amplitude, interference occurs, resulting in a smaller or zero resultant amplitude.
5. Wave superposition only applies to transverse waves.
True
False
6. The individual waves are permanently altered after they superpose.
True
False
7. Briefly explain the difference between constructive and destructive interference.
8. Describe a real-world example of wave superposition.
