DEFINE DOPPLER EFFECT ?
with Fully explanation with Figure​

Answer 1

Explanation:

$\huge\fcolorbox{red}{yellow}{ANSWÉR}$

Doppler Effect in physics refers to the change in wave frequency during the relative motion between a wave source and its observer.

f_{o} = observer frequency of sound

v = speed of sound waves

v_{o} = observer velocity

v_{s} = source velocity

f_{s} = actual frequency of sound wave

${\rm{\pink{\underline{\underline{\huge⚘{MORE/ TO /KNOW⚘}}}}}}$

Vr = speed of the receiver relative to the medium, +c if the receiver is moving towards the source, -c if the receiver is moving away. Vc = speed of the source relative to the medium, +c if the source is moving away -c if the source is moving towards the receiver

● Definition ⬇

Doppler Effect refers to the change in wave freq-uency during the relative motion bet-ween a wave source and its ob-server. For in-stance, when a sound object moves towards you, the freq-uency of the sound waves in-creases, leading to a higher pit-ch.

Encyclo-paedia Britan-nica's editors overse subject areas in which they have ex-tensive know-ledge, whether from year of experience gained by working on that con-tent or via study for an advanced de-gree.
