What will result in the best axial resolution long pulse length short pulse length low pulse repetition frequency or high pulsed repetition frequency?
== == In diagnostic ultrasound axial resolution is influenced by a number of factors including transmission pulse length and frequency of the probe. For best axial resolution short pulses are used - long pulses can potentially improve the signal to noise ratio but their use often results in "range side lobes", effectively a reduction in axial resolution. Pulse repetition frequency (PRF) is a separate issue to axial resolution however high frequency probes are able to have a higher PRF (resulting in higher frame rates) than low frequency probes due to the higher rate of absorption of the higher frequency signals.
Does having your period lower your pulse?
No, your period has no effect on your pulse.
Do hiccups effect pulse rate?
No, they're just an acid reflex and don't have any effect on your pulse.

Measure of clarity of an image?
For practical purposes the clarity of the image is decided by its spatial resolution, not the number of pixels in an image. In effect, spatial resolution refers to the number of independent pixel values per unit length.
What property of a wave is defined as the length of time between pulses?
pulse length
How you can use a simple pendulum to measure the pulse rate?
Pulse and pendulum According to his first biographer Viviani, Galileo experimented with synchronizing two clocks -- the human pulse, and a pendulum -- in his student days at Pisa. The resulting invention, the "pulsilogium", represented the pulse rate as the length of the pendulum. Try making a pulsilogium: adjust the length of a pendulum so that its rate of swinging agrees with your own pulse. Mark the length. Then adjust the same pendulum for your lab partner's pulse -- is there a detectable difference in pulse rate? 2. Pendulum length and frequency It would be good to know what pendulum length means as a frequency (or pulse rate). http://www.mtholyoke.edu/courses/mpeterso/galileo/time2.htm
What does the energy of the wave pulse depend on?
The energy of the wave pulse depends on wave length and frequency.
Does the age of a person have any effect on their pulse?
Yes, the pulse tends to slow with aging.
