The second sound of the cardiac cycle, commonly referred to as the S2 sound, occurs when the aortic and pulmonary valves close at the end of ventricular systole as blood is forced out of the ventricles and into the aorta and pulmonary artery. This sound marks the end of the systole phase and the beginning of diastole.

What is the unit to measure frequency of a sound wave?
The unit to measure the frequency of a sound wave is hertz (Hz). One hertz is equal to one cycle per second. Frequency is a measure of how many wave cycles occur in a given time period, typically measured in seconds. In the context of sound waves, frequency determines the pitch of the sound, with higher frequencies corresponding to higher pitches.
If a note is 400hz. how many sound waves pass point per second?
400. Hz (hertz) means cycles per second.
What is the Speed of sound formula for beats per second?
The speed of sound is not directly calculated using beats per second; rather, beats occur when two sound waves of slightly different frequencies interfere with each other. The beat frequency (in beats per second) can be determined using the formula: ( f_{beat} = |f_1 - f_2| ), where ( f_1 ) and ( f_2 ) are the frequencies of the two sound waves. The speed of sound in a medium, however, is typically calculated using the formula ( v = f \lambda ), where ( v ) is the speed of sound, ( f ) is the frequency, and ( \lambda ) is the wavelength.
Is the speed of sound 87000 Miles per second?
No, the speed of sound (at sea level) is only about 0.213 mile per second.
Is light faster than sound or sound is faster than light?
Light is faster than sound. Light travels through empty space at a speed of about 186,282 miles per second (299,792 kilometers per second), whereas sound travels through air at about 1,125 feet per second (343 meters per second).
Cardiac cycle when do you hear the first heart sound snd second?
when the ventricles closes and between the atria and the ventricles.
Are cycle per second the amount of waves per second?
Yes, a cycle is from start to finish of a wave function (until it repeats again)
The first sound of a cardiac cycle occurs when?
closure of the mitral and tricuspid valves.
What is occurring during the diastolic period?
Diastole is the phase in the cardiac cycle that allows filling of blood into the ventricle. It corresponds to the lower number in the blood pressure measurement. A normal upper limit of the blood pressure falls in the range less than 120/80 mm Hg. Above this value, it is considered pre-hypertension based on The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.During the diastolic period the ventricle is in the fifth phase of the cardiac cycle. This phase is termed isovolumetric relaxation which occurs immediately after the second heart sound. In this phase, all valves of the heart are closed. The volume of blood in the ventricle during this phase of the cardiac cycle remains constant. Following the fifth phase of the cardiac cycle is the rapid filling of blood into the ventricle. This cycle corresponds to the opening of the mitral and tricuspid valves located between the left and right atria and ventricle, respectively. The next phase of the cardiac cycle, called diastasis, is the longest phase of the cardiac cycle. In this cycle, the ventricle continues to fill with blood but at a much slower rate. The final phase of diastole corresponds to the first phase of the cardiac cycle. In this phase of the cardiac cycle, the atria contracts to provide additional filling of blood into the ventricle. After the final phase of diastole, the systolic phase of the cardiac cycle begins.
What is the unit to measure frequency of a sound wave?
The unit to measure the frequency of a sound wave is hertz (Hz). One hertz is equal to one cycle per second. Frequency is a measure of how many wave cycles occur in a given time period, typically measured in seconds. In the context of sound waves, frequency determines the pitch of the sound, with higher frequencies corresponding to higher pitches.
Why is lub dubb produce?
The "lub-dub" sound of the heartbeat is produced by the closing of the heart valves. The "lub" (first heart sound) occurs when the atrioventricular valves close as the ventricles contract, while the "dub" (second heart sound) happens when the semilunar valves close as the ventricles relax. This cyclical opening and closing of the valves during the cardiac cycle generates the characteristic sounds associated with a heartbeat.
What is the vowel sound in cycle?
The Y in cycle is a long I vowel sound, as the E is silent.
What is the frequency of a sound a measure of?
The basic unit of a frequency is called Hertz. One Hz is one cycle per second. This applies to frequencies such as sound, radio, and light.
A frequency of one sound wave per second is called?
Frequency is related by 1/Time. The unit is hertz (hz). One sound wave a second would yield a frequency of 1 hz.
What unit is sound frequency measured in?
Frequency is measured in hertz. Cycles per second.
What is the origin of heart sounds?
Heart sounds originate from the closure of heart valves during the cardiac cycle. The first heart sound (S1) is produced by the closure of the mitral and tricuspid valves, while the second heart sound (S2) is caused by the closure of the aortic and pulmonary valves. These sounds can be heard using a stethoscope during a physical examination.
What does the frequency of sound measure?
The frequency of sound is measured in "Hertz (Hz)".
