What is the baseline of a wave called?
Intervals contain waves. Segments refers to the baseline between the end of one wave and the beginning of the next wave. Segments are the lines between waves.
What is the resting line of a wave?
The line through the center of the wave is the resting position of the medium if there was no wave passing through. We can determine a number of wave properties from the graph. The amplitude of a wave is a measure of the displacement of the wave from its rest position.
Which line represents the rest position?
The dashed line drawn through the center of the diagram represents the equilibrium or rest position. The crest of a wave is the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position.
What is the main difference between transverse and longitudinal waves?
Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
What is the line of origin of a wave?
#__1_ = line of origin Signifies the original position of the medium. #__3_ = wavelength The distance between two consecutive crests. #__4_ = amplitude The distance from the line of origin to a crest or trough of a wave.
What is amplitude physics?
amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.
Where is the rest position of a transverse wave?
The resting position of a particle of the medium is where the particle would be in the absence of a wave. The Figure below show the amplitudes of two different types of waves: transverse and longitudinal waves. In a transverse wave, particles of the medium move up and down at right angles to the direction of the wave.
What does rest to the bottom of the wave measure?
The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position.
What is the rest axis?
The rest axis is drawn to show the rest position of the medium? In a longitudinal wave, a rest axis would apply only if we are considering a two-dimensional wave. There would be lines, perpendicular to the direction of travel of the wave, that would consist of particles that are undisturbed at a given moment.
What is complete wave?
The wavelength of a wave is simply the length of one complete wave cycle. And the length of one such spatial repetition (known as a wave cycle) is the wavelength. The wavelength can be measured as the distance from crest to crest or from trough to trough.
Is a sound wave transverse or longitudinal?
Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.
What is the difference between a progressive wave and a standing wave?
A progressive wave is a wave that travels continuously in a medium in the same direction without a change in amplitude, while a standing wave is a wave in which the position of the maximum and minima do not travel, but remain in place.
What causes rebreathing waveform with baseline elevation of ETCO2?
Rebreathing can also appear with the following waveform with baseline elevation, which is due to inadequate exchange of CO2. Picture from http://www.paramedicine.com/pmc/End_Tidal_CO2.html. Increased EtCO2 can be due to four components: Increased CO2 production (fever, NaHCO3 administration, tourniquet release, and overfeeding syndrome).
What is the pressure time waveform in the respiratory system?
time e The pressure-time waveform is a reflection of the pressures generated within the airways during each phase of the ventilatory cycle. At the beginning of the inspiratory cycle, the ventilator has to generate a pressure P res to overcome the airway resistance.
What are the 4 phases of normal baseline?
NORMAL CAPNOGRAM. 4 phases. Phase I (inspiratory baseline) reflects inspired gas, which is normally devoid of carbon dioxide. Phase II (expiratory upstroke) is the transition between VD ana, which does not participate in gas exchange, and alveolar gas from the respiratory bronchioles and alveoli. Phase III is the alveolar plateau.
What is capnography waveform interpretation used for?
Capnography waveform interpretation can be used for diagnosis and ventilator-trouble shooting.
