Relationships and Equations Flashcards
How are period and frequency related?
Inversely related/reciprocal. As frequency increases, period decreases.
How are amplitude and power related?
Power is proportional to the wave’s amplitude squared
How is intensity related to power?
Directly related. When a wave’s power is doubled, the intensity is doubled.
How is intensity related to amplitude?
Intensity is proportional to the wave’s amplitude squared
How are wavelength and frequency related?
Inversely related. As frequency increases, wavelength decreases.
How are stiffness and speed related?
Directly related. As materials become stiffer, the speed of sound in the material increases.
How is density related to speed?
Inversely related. As materials become more dense, the speed of sound in the material decreases.
How is spatial pulse length related to the number of cycles in the pulse?
Directly related
How is spatial pulse length related to the wavelength
Directly related
How is spatial pulse length related to frequency?
Inversely related
How are pulse repetition period and depth of view related?
Directly related. As depth of view increases, pulse repetition period increases.
How are pulse repetition frequency and depth of view related?
Inversely related. As depth of view increases, pulse repetition frequency decreases.
How are pulse repetition period and pulse repetition frequency related?
Inversely related/reciprocal relationship. The shorter the PRP, the higher the PRF.
How is duty factor related to imaging depth?
Inversely related. Duty factor is higher when the system is imaging at shallow depths.
Equation for Period
Period (s) = 1 / Frequency
Equation for Frequency
Frequency (Hz) = 1 / Period
