A phenomenon known as three wave pulses travelling along the same string can be observed by holding one end of a string and quickly slapping the other end against a hard surface. When the string is plucked, it will vibrate and produce a tone. If the string is then quickly slapped against a hard surface, it will vibrate again and produce a second tone. If the string is then plucked a third time, the two tones will be heard together.
The three wave pulses travelling along the same string are caused by the string vibrating in different modes. When the string is plucked, it vibrates in a fundamental mode, which is the basic vibration that produces the tone. When the string is quickly slapped against a hard surface, it vibrates in a second mode, which is a higher frequency vibration that produces the higher tone. When the string is plucked a third time, the two tones will be heard together because they are both vibrations of the same string.
The three wave pulses travelling along the same string are also known as beats. Beats are created when two tones with different frequencies are played together. The two tones will create a beat frequency, which is the frequency of the tone that is created when the two tones are combined. The frequency of the beat frequency will be the difference between the two frequencies of the two tones.

How does a pulse move along a string?
When plucking a guitar string, the string vibrates back and forth between the two points of contact. The vibration of the string creates a pulse that travels down the string. The pulse moves at a constant speed, and the distance it travels in a given amount of time depends on the string’s thickness and stiffness.
The pulse moves in a wave-like pattern, and the speed of the pulse depends on the frequency of the vibration. The higher the frequency, the faster the pulse moves.
The pulse is strongest at the point of contact, and it gradually diminishes as it travels down the string. The pulse also spreads out as it travels, and the width of the pulse depends on the string’s thickness and stiffness.
When the string is plucked, the pulse travels down the string and sets the air in the room vibrating. This creates the sound that we hear.
What direction does the wave pulse travel?
A wave pulse is a wave that travels outward from a central point. The direction in which the wave pulse travels can be determined by the direction of the wave’s energy propagation. The energy of a wave pulse is propagated in a radial manner, meaning that the energy travels outward from the central point in all directions.
What is the frequency of the wave?
A wave’s frequency is how often the waveform repeats. The higher the frequency, the more rapidly the waveform repeats. Sound waves have a frequency in Hertz (Hz), which is measured in cycles per second. The human ear can hear sounds with frequencies from about 20 Hz to 20,000 Hz.
What is the amplitude of the traveling wave?
The amplitude of a traveling wave is the magnitude of its displacement from equilibrium. This is determined by the height of the wave’s crest or the depth of its trough. The amplitude is also related to the wave’s power and intensity.
What happens when two pulses meet?
When two pulses meet, they combine to create a single, louder pulse. This happens because the two waves add together, creating a new wave that is taller than either of the original waves.
What is pulse in wave motion?
Wave motion is created when a disturbance moves through a medium. This disturbance can be in the form of a vibration, a sound wave, or an electromagnetic wave. One type of wave motion is pulse wave. Pulse wave is created when the medium is disturbed and then returns to its original state. This creates a pulse or a spike in the wave.
The amplitude of a pulse wave is the height of the pulse. The pulse wave can be either positive or negative. A positive pulse has a greater height than the original wave, while a negative pulse is shorter than the original wave.
The duration of a pulse wave is the length of time it takes for the pulse to reach its peak and return to its original state. The speed of a pulse wave is the speed at which the pulse travels through the medium.
Pulse waves are often used to measure heart rate. When the heart beats, it creates a pulse wave that travels through the blood vessels. The pulse wave can be used to measure the heart rate by counting the number of pulse waves per minute.
What is a pulse in a wave?
A pulse in a wave is an abrupt change in the amplitude of a wave. This change can be either up or down, and it causes the wave to move from one extreme to the other. The pulse is what makes the wave move, and it is what people hear when they listen to sound waves.
