Can someone help please?

Answer 1

with?

Answer 2

that

Answer 3

i think its A. The higher the frequency, the more energy in the wave

Answer 4

the sum of energy in a wave is proportional to its amplitude and frequency

since amplitude is inversely proportional to energy, the lower the amplitude, the greater the energy AND the more frequent is the frequency, the higher is the energy

so A is indeed the correct answer.
