What properties of sound change with respect to any change in frequency and amplitude?
a) Pitch-amplitude; echo-frequency
b) Echo-amplitude; loudness-frequency
c) Pitch-amplitude; loudness-frequency
d) Loudness-amplitude; pitch-frequency
Answers
Answer:Answer. Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies. In the visual system, a light wave's wavelength is generally associated with color, and its amplitude is associated with brightness....
Explanation:
(d) Loudness-amplitude; pitch-frequency.
The properties of sound that change with respect to any change in frequency and amplitude are pitch and loudness.
Pitch is the perceived highness or lowness of a sound, and it is directly related to the frequency of the sound wave. As the frequency of a sound wave increases, the pitch of the sound also increases, and vice versa. Therefore, any change in frequency will result in a change in pitch.
Loudness is the perceived volume or intensity of a sound, and it is directly related to the amplitude (or height) of the sound wave. As the amplitude of a sound wave increases, the loudness of the sound also increases, and vice versa. Therefore, any change in amplitude will result in a change in loudness.
Echo, on the other hand, is not directly related to frequency or amplitude, but rather to the reflection and interference of sound waves. When sound waves reflect off surfaces and interfere with each other, they can create echoes or reverberations.
In summary, the correct option is (d) Loudness-amplitude; pitch-frequency.
