Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does the law of reflection state?
- The angle of incidence is less than the angle of reflection
- The angle of incidence equals the angle of reflection
- The angle of incidence is greater than the angle of reflection
💡 Hint: Imagine how light reflects off a mirror.
Question 2
True or False: Waves reflecting off a free boundary always change phase.
- True
- False
💡 Hint: Recall the differences between fixed and free boundaries.

Challenge Problems
Push your limits with challenges.
Question 1
If a sound wave approaches a cliff at an angle of 45 degrees, what will be the angle of reflection? Assume the cliff surface is fixed.
💡 Hint: Apply the rule: angle of incidence equals angle of reflection.
Question 2
A wave reflects off a free boundary and then meets a fixed boundary. Describe the resultant wave behavior.
💡 Hint: Consider the effects of each boundary on the wave's phase.
