Define the following terms:
a) Amplitude b) Frequency c) Pitch d) Time period
Answers
Answer:
a) Amplitude
The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period). There are various definitions of amplitude (see below), which are all functions of the magnitude of the differences between the variable's extreme values. In older texts, the phase of a period function is sometimes called the amplitude
b) Frequency
Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. ... The hertz measurement, abbreviated Hz, is the number of waves that pass by per second.
c) Pitch
noun. relative point, position, or degree: a high pitch of excitement. ... the highest point or greatest height: enjoying the pitch of success. (in music, speech, etc.) the degree of height or depth of a tone or of sound, depending upon the relative rapidity of the vibrations by which it is produced.
d)Time period
The time required by a body exhibitting periodic motion to complete one period is known as the time period. The S.I. unit is second. Frequency : The number of times a body exhibits unique motion (each period) in one second is known as frequency. The S.I. unit is per second or hertz
