ocean waves cause water to push air into or pull air out of the device. the air movement causes a turbine on the device to produce electricity in a
generator.
which defines a wave condition that will result in an increase in the production of electricity?
○ increase in the distance between the waves
○ decrease in the distance the waves travel in a period of time
○ increase in the height of the waves
○ decrease in the number of waves entering the column in a period of time

Explanation:

The device converts ocean wave energy to electrical energy via air movement from water column changes. Higher waves (greater height) will cause more significant water column movement (rising/falling), leading to more air movement, which drives the turbine more to produce more electricity. Other options: increasing wave distance (wavelength) or decreasing wave travel distance (speed) or wave number won't increase energy input as much as higher wave height, since wave energy is related to amplitude (height) squared.

Answer:

increase in the height of the waves
