Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Which wave shows the sound from a young girl speaking quietly to her dog? Consider both the frequency and amplitude of the sound wave.

Answer 1

-- A little girl has a voice with high pitch (high frequency)

-- Speaking quietly, she's making sounds with low amplitude

The wave with the high frequency and low amplitude is C .

Answer 2

Answer: Option (C) is the correct answer.

Step-by-step explanation:

Since it is given that the girl is speaking quietly therefore, it means that there will be very less loudeness in her voice. So, amplitude will be less.

Whereas pitch of her voice will be more so that the dog can clearly hear him. This means frequency of her voice will be more.

Thus, we can conclude that option (C) depicts the correct wave.
