The lub sound occurs around the peak of the R wave in an ECG because it is associated with closure of the mitral and tricuspid valves, which happens at the beginning of ventricular contraction. This coincides with the R wave, which represents ventricular depolarization and the onset of ventricular systole.
The height of half a sound wave is called the amplitude. It represents the maximum displacement of the wave from its rest position and is a key factor in determining the loudness of the sound. In a graphical representation of a wave, the amplitude is measured from the center line (equilibrium) to the peak (or trough) of the wave.
A sound wave that consists of places with higher pressure is called a compression. In a sound wave, compressions occur when particles of the medium are pushed closer together, resulting in areas of increased pressure. These alternating compressions and rarefactions (areas of lower pressure) propagate through the medium, allowing sound to travel.
The high point of a wave is its creast or peak.
The frequency of this sound wave is very near constant.
The result of a reflected sound wave is obviously an echo.
The period of a 261 Hertz sound wave is 0.000383 Seconds
The peak of a sound wave is the instant at which the particles in the conducting medium are displaced farthest from their rest position. Note that the peak ... or any other point in the wave ... moves through the medium, at the speed of . . . . . wait for it . . . . . sound !
The wave length is the distance between the peak of one sound pressure or electrical wave and the peak of the next. It's also known as one cycle (1 Hertz).
Wavelength
In reference to sound, a cycle typically refers to the complete wave pattern of a sound wave going from its highest point (peak) to its lowest point (trough) and back to its starting point. This complete cycle represents one full oscillation of the sound wave.
Sound is a longitudinal wave, meaning that the vibrations occur in the same direction as the wave travels.
The area of a sound wave that represents a compression is the region where the particles are closest together, resulting in high pressure. This is typically seen as the peak or crest of the wave.
A sound wave of high pressure is called a compression or a peak in the wave's amplitude. These high-pressure regions correspond to the portions of the wave where air particles are densely packed together.
The height of half a sound wave is called the amplitude. It represents the maximum displacement of the wave from its rest position and is a key factor in determining the loudness of the sound. In a graphical representation of a wave, the amplitude is measured from the center line (equilibrium) to the peak (or trough) of the wave.
The distance between two points on a sound wave is known as the wavelength. It is the physical length of one cycle of the wave, which is typically measured from one peak (or trough) to the next. The wavelength of a sound wave is inversely proportional to its frequency.
During rarefaction, air particles are spread apart, creating a low-pressure region. This causes the sound wave to be at a minimum amplitude. During compression, air particles are pushed together, creating a high-pressure region and a peak in the sound wave's amplitude. These alternating patterns of rarefaction and compression create the vibrations that we perceive as sound.
The peak of a sound wave where the lowest air pressure occurs is called the rarefaction. This is the point where the air molecules are spread out, creating a region of decreased pressure compared to the surrounding air.
