question 15 (3 points)\nlisten\nbelow are illustrations of waves. study the illustrations and answer the questions that follow.\nwhich wave has the least energy?\nthey all have the same frequency.\nc\na\nb
Answer
Explanation:
Step1: Recall energy - amplitude relation
The energy of a wave is proportional to the square of its amplitude. Larger amplitude means more energy.
Step2: Compare amplitudes
Wave C has the smallest amplitude among A, B and C. Since energy is related to amplitude as mentioned above, the wave with the smallest amplitude has the least energy.
Answer:
C
