doppler
word
Definition
Doppler refers to the Doppler effect, a change in the frequency of sound, light, or other waves as the source and observer move relative to each other. In medicine, it often means a type of ultrasound test that measures blood flow.
Usage & Nuances
Most often used in scientific or medical contexts. In everyday speech it usually refers to a medical ultrasound ('Doppler scan'). The term comes from the Doppler effect, but 'a Doppler' often means the test, not the effect itself.
