Question

High-pitched sounds are characterized by sound waves which have a __. List all that apply
A) High frequency
B) Low frequency
C) Long wavelength
D) Short wavelength
E) High amplitude
F) Low amplitude

So from what I understand, high-pitched sounds have high frequency and thus short wavelengths but I'm rather confused about the amplitude. Can someone please explain?

Answer 1

You're right. Frequency is characterized as how fast a wave oscillates, whereas amplitude is related to the amount of energy carried by a wave. The more energy that is put into a sound wave, the louder the sound is perceived while the wave oscillation remains the same.

Answer 2

high pitch - high frequency or low wavelength.
As said by danmill1, amplitude gives an idea of loudness of the wave.

Answer 3

I understood what amplitude is but I couldn't understand how it fit into the question. Turns out that I didn't need to add it in at all! Thank you both very much for your responses!
