CBSE Class 12-science Answered

how can we determine the energy of a wave?
Asked by radha gupta | 28 Feb, 2011, 12:00: AM
Expert Answer
Dear student,
 
To determine the amount of wave energy, use an equation to calculate the amount of energy based on the height of a wave.  First, determine the amount of energy for every square meter of wave, the energy (joules) is equal to 1260.6 times the square of the wave height.
 

Wave Energy = 1260.6 (Wave Height)2

2.  To determine the Total Energy in a wave, calculate the total surface area of the wave and multiply that by the wave energy.

Total Energy = Wave Energy (surface area of wave)

For example, calculate the energy for an average open water wave that is 2 meters high, 7 meters wide and 500 meters long:

Wave Energy = 1260.6 (Wave Height)2
Wave Energy = 1260.6 (2)m2
Wave Energy = 1260.6 (4)m2
Wave Energy =  5042.4 Joules/m2
 
 
Hope this helps.
