The energy supplied to a speaker is increased. What will happen to the sound the speaker produces? A) The sound will be lower pi
tch. B) The sound will become a high pitched squeal. C) The sound will be louder or greater amplitude. D) The sound will remain unchanged if the speaker is not changed.
Answer: The sound will be louder or greater amplitude.
Explanation: The energy input in the speaker relates directly to the intensity of the soundwave that the speaker creates, and the intensity of a soundwave is directly related to the "volume" of the sound. This is because the energy imput is used in the amplifiction proces, as more energy comes, bigger is the amplification of the sound.
So the correct option is the C: The sound will be louder or greater amplitude.
