FINAL

So I'm going to be describing the Doppler effect.

So, some basics, what is it, the changes in frequency

of any kind of light or sound wave produced by

a moving source in respect to the observer.

How does it work?

It works on both light and sound objects.

For instance, when a sound object moves towards you, the

frequency of the sound waves increases, leading to a higher

pitch. If it moves away from you, the frequency of

the sound waves decreases in the pitch comes down.

So some examples, it can be shown through sound and

light. The first example is a sound one, the pitch

of a siren as high as an ambulance approaches than

lower as the ambulance passes.

The next one is going to be a light example,

when a star moves towards us, it's wavelengths get compressed

and its spectrum becomes slightly bluer.

The opposite happens when the star moves away from us.

It's spectrum looks slightly redder.

So how to find the Doppler effect when finding the

Doppler effect, there are multiple different equations for different scenarios.

You can use their five different equations.

The first two are when a source is moving towards

and away from the observer, the next two are the

observer moving toward and away from the source, and then

the last one is the observer and source moving at

the same time.

All of them mentioned equations are ways to solve the

Doppler effect through rational equations.

So some extra things.

So in conclusion, when wave energy like sounder radio waves

travels from two objects, the wavelength can seem to be

changed if one or both of them are moving, this

causes different pitches, et cetera.

So, as a demonstration, I want you to close your

eyes and just listen.

Mhm as you notice, it gets louder when the clapping

is closer to the speaker and then it lowers its

pitch as it starts to move away.

So some things that the Doppler effect are used with

in real life.

There's sirens, astronomy, radars, flow management, audio medical imaging and

blood flow management, vibration measurement, satellite communication and velocity profile

management. And there's also tons more.

And that's the Doppler effect.
