Answer:
1.21 times
Explanation:
The energy of a wave is proportional to the square of the amplitude of the wave.
Mathematically:
e & a²
where
E is the energy of the wave
A is its amplitude
In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as
A=1.1A
Therefore, this means that the energy of the wave increases by a factor:
E' & A'²= (1.1A)² =1.1²A² =1.21A² =
1.21E
Therefore, the energy of the wave increases by a factor 1.21.:
