Question

Henri draws a wave that has a 4 cm distance between the midpoint and the trough. Geri draws a wave that has an 8 cm vertical distance from the bottom of the trough to the top of the crest. Which statement best describes the energy in Henri and Geri’s waves? Henri’s wave has a higher amplitude and more energy. Henri’s wave and Geri’s wave have the same amplitude and the same energy. Henri’s wave and Geri’s wave have the same amplitude, but Geri’s has more energy. Geri’s wave has a higher amplitude and more energy.

Answer 1

Step-by-step explanation:

Answer 2

Henri’s wave and Geri’s wave have the same amplitude and the same energy

Step-by-step explanation:

The amplitude of a wave is the distance between the midpoint and the trough (or the crest). This is equivalent to half the distance between the trough and the crest. Therefore:

• amplitude of Henri's wave: 4 cm

• amplitude of Geri's wave: 8/2 = 4 cm

The energy of a wave is directly proportional to its amplitude.
