Physics Review Question Unit: Waves Year: 1993 Question#: 41 Question: Two waves have the same frequency. Which wave characteristics must also be identical for both waves? (1 ) phase (2 ) amplitude (3 ) intensity (4 ) period What is this question really asking? Explanation by: Danielle [ Return to question menu ] Answer 1 phase INCORRECT A phase is points on wave cycles that are displaced from their rest position by same amount and moving in the same direction. return to top Answer 2 amplitude INCORRECT Amplitude is the maximum change in position of a particle of the medium from its rest position during one wave cycle return to top Answer 3 intensity INCORRECT Intensity has nothing to do with wave characteristics return to top Answer 4 period CORRECT Period is the time required for an entire wave cycle to pass a given point of medium. This is the time taken for completion of a single vibration. Period is the inverse of frequency. return to top What's this question really asking? If two waves have the same frequency, what else must be identical? return to top |
