What is the velocity of a radio wavelength of 3m?
If u meant radio wave, then velocity of all electromagnetic wave is 3*108 m/s. Hence velocity of radio wave will be the same ,as it as an em wave, irrespective of its wavelength.
What is units for wave speed?
The same unit meant for velocity ie m/s.
What is meant by the wave-particle duality of light?
It means that light has features of both waves and particles.
What is de-Broglie theory?
The theory states that both matter and light exhibit wave and particle nature which leads tointerference effect i.e; when the wavelenght is <<<< the scale which we use it ,behaves as particle and when wavelenght >>>>the scale it behaves as wave.
What is meant by the frequency of a wave what is the unit?
The frequency of a wave is the number of complete waves that pass a fixed point in one second. The unit is "Hertz" or "Cycles". The dimension is "per second". (Reciprocal time.)
What does a poor R wave progression mean in a cardiogram?
Poor R wave progression is a vague term used to describe the transition in voltage in the precordial leads of an electrocardiogram (ECG). It is not a diagnosis but simply describes a pattern frequently noted. In a "normal" individual there is a progressive increase in the magnitude of the voltage in the leads from V1 to V4. When the peak voltage occurs later than V4 it is considered diminished or delayed. The normal criteria are very old and were likely based upon pathologic data. Current ECG technology includes computer interpretation. This particular pattern is usually reported out as "cannot rule out anterior myocardial infarction." The placement of the precordial leads is paramount in obtaining a reliable ECG pattern. Frequently the precordial leads are placed in the wrong position in haste to obtain the electrocardiographic tracing. Women particulary large breasted are most likely to have the leads improperly placed as the left breast usually overlies the 4th and sometimes the 5th intercostal space (where the leads should be placed). In summary, the term poor R wave progression is a vague term and not a diagnosis. Verification of proper leads placement should be the first response followed by echocardiography if there remains concern that there has been prior myocardial injury.
Poor r wave progression v2 v4?
Anterior MI
Diagnosis for poor r wave progression v1-v4?
Poor R wave progression is a vague term used to describe a variation in the pattern formed by the QRS complexes in the chest or precordisl leads. The QRS complex represents the upward and downward deflections denoting the electrical discharge with each heartbeat. Normally the R wave is taller than the S wave by the 4th lead (V4). If the transition does not occur until the 5th or 6th precordisl lead then this is commonly referred to as poor R wave progression. It is used as a distinction from clearly normal patterns and clearly abnormal patterns. It may be found in normal hearts and can frequently be caused by improper placement of the electrodes during the recording of the ECG tracing.
If Sine wave A and sine wave B are each ten kHz but B is delayed by 8.5 micro seconds from A The phase difference between the waves is?
30.6 degrees
Did Seabiscuit have thoroughbred best wave?
I have no idea what is meant by best wave, and have never heard that in reference to Seabiscuit.
When the crest of one wave aligins with the trough of another wave the result is?
It leads to destructive interference. So resultant displacement becomes minimum.
When will Google Wave be released?
Google Wave released an invitation-only preview, that started on September 30th 2009. The full release was expected in late 2009, but has now been delayed to 2010.
What can iron deficiency anemia do to your ecg?
flat t wave in chest leads --- --s.t.
Are the wave creation 11 shoes stylish?
Wave creation 11 shoes are specifically meant for runners with some extra weight or flat feet. They may not look stylish but work for what they are meant for.
What is meant by third wave countries?
Countries that got democracy post 1974 are called third wave countries. e.g. nepal
What is meant by reflection loss in electromagnetic waves?
It means that when the wave is reflected, not all of the wave energy is reflected - rather, part of the wave is either absorbed or simply let through.
What are T wave abnormalities on anterolateral leads?
t-wave adnormalities can be related to ischemia in the anterolateral muscle of the heart or could be caused by other factors such as electrolyte abnormalities.
