Exam-style question
Try this first
Two waves traveling in the same medium interfere with each other. If wave A has an amplitude of 3 cm and wave B has an amplitude of 4 cm, what is the maximum amplitude of the resultant wave when they interfere constructively?.
Model answer
What a good answer should say
- The maximum amplitude of the resultant wave is 7 cm.
Explanation
Why this works
This question tests the application of the principle of superposition in a practical scenario. The calculation involves adding the amplitudes of the two waves, demonstrating how constructive interference works.
