Question

Which wave, A or B, has lower energy?

A, because it has a higher amplitude
B, because it has a higher amplitude
A, because it has a lower amplitude
B, because it has a lower amplitude





answer is C for those who saw the other question

Answer 1

A, because it has a lower amplitude

Step-by-step explanation:

Energy of wave is represented in the formula:

e = 1/2kA^2

where:

---> k is constant

---> a is amplitude

hence, the increase or decrease of energy depends on the amplitude of the wave

if the amplitude is less, than the energy is also less.
