Question

keep going! answer the questions below. you can assume that the waves in each set are traveling at the same speed.

1. wave e wave f

which wave has more energy? explain why.

1. wave g wave h

which wave has more energy? explain why.

1. the more energy a sound wave has, the louder the sound. look at the two sound waves below.

wave j wave k
which wave represents the volume being turned up, wave j or wave k? explain.

Explanation:

Step1: Recall wave - energy relationship

The energy of a wave is proportional to the square of its amplitude. Larger amplitude means more energy.

Step2: Analyze Wave E and Wave F

Wave F has a larger amplitude than Wave E. So Wave F has more energy.

Step3: Analyze Wave G and Wave H

Wave G has a larger amplitude than Wave H. So Wave G has more energy.

Step4: Analyze Wave J and Wave K

Wave J has a larger amplitude than Wave K. Since more energy in a sound - wave means louder sound, Wave J represents the volume being turned up.

Answer:

1. Wave F has more energy because it has a larger amplitude.
2. Wave G has more energy because it has a larger amplitude.
3. Wave J represents the volume being turned up because it has a larger amplitude, indicating more energy and a louder sound.
