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

Explanation :

It is given that,

Henri draws a wave that has a 4 cm distance between the midpoint and the trough (fig).

Geri draws a wave that has an 8 cm vertical distance from the bottom of the trough to the top of the crest (fig).  

So from the figure, it is clear that the amplitude of both Henri's and Geri's waves are same i.e. 4 cm.

Energy of the wave depends on the amplitude of the wave. So, Both wave has the same energy.

So, the correct option is (b) "Henri’s wave and Geri’s wave have the same amplitude and the same energy".

ill do it for 100, also this isnt 80 its 40
