Like if you grab hold of spring and shake it back and forth a lot. Pulse, on the other hand, often refers to some type of one-time disturbance. Like shaking the spring only once.
Of course there will be overlap or ambiguities in these terms. I doubt there's any agreed-upon precise definition of these. A pulse is just a special type of wave - a solitary wave. And solitary waves that dissipate a minor amount of energy into the medium, have low dispersion, and are able to maintain their shape over distance are called ' solitons '.
A vortex ring is a good and interesting example of a solition. Considering Fourier analysis, all types of waves, including pulses can be modeled by mathematics.
A single vibration is called pulse and continued vibration of a particle in medium is called wave. A pulse refers to a disturbance that travel from one location to another location through a medium. While, A wave refers to the disturbance or variation that travels through the medium. Waves come in two kinds, longitudinal and transverse.
Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
Use a watch with a second hand, or look at a clock with a second hand. Count the beats you feel for 10 seconds. Multiply this number by six to get your heart rate pulse per minute. There is a big difference between what the wave does and what the particles in the medium do. As the wave travels through the medium, the particles of the medium oscillate in response to the wave.
In a uniform medium, the wave travels at constant speed; each particle, however, has a speed that is constantly changing. Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the product of its wavelength and frequency number of vibrations per second and is independent of its intensity.
If the process occurs repeatedly, it is known as an oscillation, and the oscillations lead to waves. In physics, a sudden variation in a quantity that is a constant usually is known as a pulse. This term often refers to a change in position in a medium, seen and described as amplitude, due to a vibration. A series of such sudden variations is also known as a pulse.
A periodic disturbance in a medium or space is known as a wave. The disturbance can be regular or irregular. Waves are the main method of energy transfer in the nature. Whenever excess energy is released from a system or object, it is carried away by a wave. Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.
Periodic motion is a motion which repeats itself after a regular interval of time. Examples of periodic motion are: i Revolution of planets around the sun. Explanation: Motion which repeats itself after certain intervals is called periodic motion.
Since the motion of a swing also repeats after regular intervals so, the motion of the child on a swing is periodic. When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction between the air and the swing and between the chains and the attachment points slows it down and eventually stops it.
