which sound would be louder? a.) a wave with an amplitude of 0 b.) a wave with an amplitude of 0.1 c.) a wave with an amplitude of 1.0 d.) a wave with an amplitude of 0.5

Answer 1

If some sound is represented by a wave such as a sine or cosine wave,
the amplitude of the trig function affects the loudness of the sound, the period of the trig function affects the pitch of the sound.

so the larger the amplitude, the louder the sound.
What is the greatest amplitude given?

Answer 2

loudness is represented by the log of the square of the ampliude. So the greater the amplitude, the greater the "loudness".

Answer 3

1,0
