Interference.
When two or more waves meet, they can interfere with each other, resulting in effects such as constructive interference (when the amplitudes of the waves add up) or destructive interference (when the amplitudes cancel out). This phenomenon is called wave interference.
This effect is called the Doppler effect. It occurs when there is relative motion between the source of a sound (like a train whistle) and an observer. As the train approaches, the sound waves are compressed, resulting in a higher pitch, and as it moves away, the sound waves are stretched, causing a lower pitch.
The Doppler effect can be observed with both longitudinal waves, like sound waves, and transverse waves, like light waves. The effect describes the change in frequency of a wave as the source or observer moves relative to each other, resulting in a shift in the perceived wavelength of the wave.
A disturbance involving the transfer of energy from place to place is called a wave. Waves can be classified as mechanical waves, which require a medium to propagate (e.g., sound waves), or electromagnetic waves, which can travel through a vacuum (e.g., light waves).
The Doppler effect is noticeable when there is relative motion between a source of waves (such as sound or light) and an observer. This is commonly experienced when an object emitting waves moves towards or away from an observer, resulting in a shift in frequency or pitch of the waves.

The Doppler effect is the change in frequency of waves (such as sound or light) due to the relative motion between the source of the waves and the observer. When an object is approaching, the waves are compressed, causing a higher frequency, resulting in a higher pitch for sound waves or a blue shift for light waves. When an object is moving away, the waves are stretched, causing a lower frequency, resulting in a lower pitch for sound waves or a red shift for light waves.
When a combination of waves come together to form a larger wave, it is called interference. Interference can be constructive, where the waves reinforce each other and the resulting wave is stronger, or destructive, where the waves cancel each other out and the resulting wave is weaker.
The Doppler effect affects sound waves perceived by humans. As a source of sound moves closer, the waves are compressed, leading to a higher pitch. Conversely, as the source moves away, the waves are stretched, resulting in a lower pitch perception. This phenomenon is commonly experienced with passing ambulances or sirens.
The change in sound tones as a car moves by is due to the Doppler effect. When the car approaches, the sound waves are compressed, resulting in a higher pitch (frequency); when the car passes and moves away, the sound waves are stretched, resulting in a lower pitch. This effect occurs because the car's motion causes the sound waves to be either compressed or stretched in relation to the observer.
A disturbance in matter that carries energy from one place to another is called a wave. Waves can be classified as mechanical, such as sound waves and ocean waves, or electromagnetic, such as light waves.
Interference occurs when two or more waves overlap at the same place and time, resulting in the waves combining with each other. Constructive interference happens when the waves align to amplify each other, while destructive interference occurs when they cancel each other out. Interference can lead to changes in the resulting wave's amplitude, frequency, or phase.
I believe you're describing "interference." But I can't be sure with the way you've phrased the question. If you're referring to sound waves, then when two sine waves of equal amplitude and frequency occupy the same space and time, but are at opposite points in their (sine) oscillation, they will interfere perfectly and cancel one another out. However, if those two waves were in the exact same space and time, and at the exact same point in their sine pattern/oscillation, then they would exhibit "constructive interference," and the amplitude of the of the new wave would be the sum of the amplitudes of the two original contributing waves (minus something negligible due to physical constraints)--the frequency would remain constant.
