The main difference between a wave and a pulse is that the wave is considered to be a continuous disturbance caused by an oscillating particle in a medium. On the other hand, the pulse is not continuous and it happens during a very short time.

How do you find pulse in physics?
The speed of a pulse, v in a long spring is given by v = ฯ ยต where ฯ is the tension in the spring and ฮผ its linear mass density. Stretch the spring tighter to increase its tension and therefore its pulse speed.
What does pulsating mean in physics?
to expand and contract with a rhythmic beat; throb. 2. physics. to vary in intensity, magnitude, size, etc.
What is pulse in sound wave?
A pulse wave is an ALTERNATING CURRENT signal, whose WAVEFORM contains both positive and negative sections. The ratio of the ‘on’ to ‘off’ times of the waveform is called the duty cycle. The pulse wave may be distinguished from the SQUARE WAVE in that the latter has a duty cycle of 1:1.
What type of wave is pulse?
A pulse wave or pulse train is a type of non-sinusoidal waveform that includes square waves (duty cycle of 50%) and similarly periodic but asymmetrical waves (duty cycles other than 50%). It is a term used in synthesizer programming, and is a typical waveform available on many synthesizers.
What is a pulse function?
The pulse button is used when you need short bursts of power at the optimum speed. This is controlled by the user which means you control how long the machine is run for. It is a useful way of avoiding over-processing.
What is the unit of pulse?
Your pulse is usually called your heart rate, which is the number of times your heart beats each minute (bpm).
What is the SI unit of pulse rate?
Answer. Answer: The medical field uses beats per minute (BPM) as the standard unit for heart rate measurements.
What is used to measure pulse?
Various methods used to measure heart rate include Electrocardiography, Photoplethysmography, Oscillometry ( Blood pressure monitor method ) and Phonocardiography. Each of these methods measures different phenomenon that occur in human body during the heart beat or cardiac cycle to determine heart rate.
What is a pulse of light?
An optical pulse is a flash of light. Lasers and related devices have been found to have an amazing potential for generating light pulses with very special properties: There is a wide range of techniques for generating pulses with durations of nanoseconds, picoseconds, or even femtoseconds with lasers.
What do you mean by pulsating current?
Definition of pulsating current : a direct current that has recurring more or less regular variations in magnitude.
What is pulse in biology?
pulse, rhythmic dilation of an artery generated by the opening and closing of the aortic valve in the heart. A pulse can be felt by applying firm fingertip pressure to the skin at sites where the arteries travel near the skin’s surface; it is more evident when surrounding muscles are relaxed.
What is a pulse phase?
The phase pulse is defined as the time integral of a frequency pulse g(t) whose support is 0 โค t โค LTs (for some integer L) and whose area is 12.
What is the source of wave pulse?
The source of a wave pulse is the periodic oscillation of the constituent particles about their mean position however the oscillation is done only one time. The motion of a hand creating waves will be going up and then coming back to same position where the time period must be really small in order to create a pulse.
What is a pulse of an oscillator?
These circuits are referred to as Pulsed Oscillators or Ringing Oscillators. They are nothing more than sine-wave oscillators that are turned on and off at specific times. Figure 1 shows the circuit diagram of a pulsed oscillator with the resonant tank in the emitter circuit.
What is pulse speed?
Pulse speed. Pulse speed is the distance a pulse travels per unit time. Quantity: Pulse speed (v) Unit name: metre per second Unit symbol: mยทsโ1. Speed is defined as the distance travelled per unit time (this will be covered in more detail in Motion in One Dimension).
Is a pulse a complete wave?
Wave pulse is a short, non periodic, wave formed by a single input of energy rather than a continuous or repeated input of energy.
What is frequency of a wave?
Frequency is defined as the number of oscillations of a wave per unit time being, measured in hertz(Hz). The frequency is directly proportional to the pitch. Humans can hear sounds with frequencies ranging between 20 โ 20000 Hz.
What are the 3 types of pulse?
- Temporal: It is felt in the head.
- Carotid: It is felt in the neck.
- Branchial: It is felt in the elbow.
- Femoral: It is felt at the groin.
- Radial: It is felt on the wrist.
- Popliteal: It is felt on the knee.
- Dorsalis pedis: It is felt on the foot.
What is the difference between pulse and impulse?
A pulse is something that you feel, an impulse is something that you cause. A “pulse” is like a heartbeat or regular (repeated) throbbing, flashing, beating, etc. “Impulse” describes a sudden or strong urge/desire to do something.
What is pulse and impulse signal?
Pulse signal is of finite width and finite amplitude like for example a rect pulse or rect pulse. Where as impulse is defined when a pulse of unit area is contracted with time base tends to zero spread and amplitude tends to infinite , providing the area under the impulse remains unity as it was in pulse.
Why do we check pulse?
Your doctor feels your pulse in order to check your heart’s rate, rhythm and regularity. Each pulse matches up with a heartbeat that pumps blood into the arteries. The force of the pulse also helps evaluate the amount (strength) of blood flow to different areas of your body.
Is 120 pulse rate normal?
A normal resting heart rate should be between 60 to 100 beats per minute, but it can vary from minute to minute.
What is a weak pulse?
Bradycardia (brad-e-KAHR-dee-uh) is a slow heart rate. The hearts of adults at rest usually beat between 60 and 100 times a minute. If you have bradycardia, your heart beats fewer than 60 times a minute.
How do you take your pulse?
press the first (index) finger and middle finger of your other hand on the inside of your wrist, at the base of your thumb โ don’t use your thumb as it has its own pulse. press your skin lightly until you can feel your pulse โ if you can’t find it, try pressing a little harder or move your fingers around.
