DIPPING IN DOPPLER

🎯The Doppler effect can be explained by considering a series of water-waves travelling out from the centre of a pond, in a circular form

🎯The frequency of the waves is related to the medium and the speed at which they are travelling. 

🎯The frequency of the waves reaching the periphery is less than the frequency nearer the centre. 

🎯If a detector was in the periphery it would detect the frequency of the waves whose frequency will be less

🎯But if the detector then started moving towards the source, the frequency would increase as the detector would be picking the waves nearer to the centre, whose frequency will be more.

🎯The Doppler effect describes the change in frequency of sound waves if the source of sound is moving in relation to the detector. The frequency is increased if the source is moving towards the detector and reduced if it is moving away.

🎯APPLICATIONS OF DOPPLER EFFECT

✔️It allows the confirmation of flow within peripheral arteries as well as in the brain, where the circle of Willis can be scanned.

✔️In echocardiography

✔️in obstetric practice when a fetal heart rate monitor is used
