Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
