What are the characteristic of a wave?
in general, a harmonically oscillating, one dimensional wave is described by the following function: f(x,t)=Acos(2phi*t/T -2phi*x/ג) where A is the amplitudes (or wave height), T is the wave's period time and ג is the wave length. these are the three basic characteristics of a wave. other characteristics can be calculated from these: the frequency f=1/T , and the speed of the wave v=גf.
Give an example of the other type of wave.?
The PR wave,QRS wave, and T wave.
How the frenquency of a wave changes when a period of the wave increases?
The frequency of a wave decreases when its period increases. The frequency (f) of a wave is the number of cycles (or vibrations or oscillations) per unit time. The SI units of frequency is the inverse seconds or hertz (Hz). The period (T) of a wave is the time it takes to complete a cycle. The frequency and period have the following relationship: frequency= 1/period f= 1/T so if the period increases, the frequency decreases.
What best describes why refraction of a wave occurs when the wave travels from one material into another?
Refraction occurs because the speed of the wave varies in different materials,sin(I)/V(I) = sin(T)/V(T)
How do you measure the frequency of a sound wave?
Capture the sound with a microphone, feed its output into an oscilloscope with a calibrated timebase. Measure the time period T of the wave on the horizontal axis, then convert it into a frequency ( = 1/T)
What does the U wave represent on an ECG?
is the electrical activity generated by the contraction of the heart muscle
What does abnormal t wave mean?
what causes abnormal t waves
What is a nonspecific st-t wave change?
Nonspecific st-t wave changes do not indicate a heart attack. These changes are often dismissed by doctors, and there is no further investigation, despite the fact that their could be a pulmonary embolism or cardiac problem.
What is r t segment?
The R-T segment is the portion of the EKG tracing from the R wave to the T wave.
What does abnormal t-wave mean?
Abnormality can be due to abnormal heart rhythms or cardiac muscle defects.
What is a T-wave?
The T wave represents the repolarization (or recovery) of the ventricles. The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period. The last half of the T wave is referred to as the relative refractory period (or vulnerable period). The T wave contains more information then the QT interval. The T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the TpeakTend interval. In most leads, the T wave is positive. However, a negative T wave is normal in lead aVR. Lead V1 may have a positive, negative, or biphasic T wave. In addition, it is not uncommon to have an isolated negative T wave in lead 3, aVL, or aVF.

The period during which the ventricles are repolarizing?
the asnwer is t wave

The frequency and period have the following relationship: frequency= 1/period f= 1/T so if the period increases, the frequency decreases.
What is the portion of the ECG that indicates ventricular repolarization?
The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
How do wave frequency and period of a wave relate?
Wave frequency f, and period of wave T are inverses, related by fT=1.
