vibrations produces wave
A secondary wave!
The amplitude of a wave produces the intensity of the wave. With a light wave, it is the intensity of the light, with a sound wave, it is how loud the sound is
a 180 degree phase shift of the incident wave in the reflected wave.
A source vibrating with simple harmonic motion produces a sinusoidal wave.
Echoes
The amplitude of a sound wave determines the volume or loudness of the note. A higher amplitude wave produces a louder sound, while a lower amplitude wave produces a quieter sound.
Sometimes it makes an echo or reverberation.
Ultraviolet
A sound wave with high amplitude produces a louder sound compared to a sound wave with lower amplitude. It is perceived as a stronger or more intense sound.
arteries
analog sensor
This is smooth muscle. It produces a wave of movement.
