No an ultrasound scan does not emit light
The piezo electric crystal transducer emits sound waves of higher frequency than that in the human audible range. The transducer then picks the reflected ultrasound from the tissues under examination.

No, it emits sound waves above the frequency range detectable by the human ear, and has a sensor that converts the reflected waves into an electrical signal that represents the structure of the tissues scanned.

No. An ultrasound emits "sound" waves.

No, it emits sound waves, kind of like radar that bounce back and produce a picture.

no
basically it has not enough energy to emit light.
it's not designed to do so. it's just measuring echoes of sound-waves in a frequency-range you cannot hear. Have that with higher energies and higher frequencies it would emit light

no-why should it-it doesn't emit radio waves either

No. It 'sees' by echoes in sound.
