Why Is The Sunset Red?


hello everyone and welcome back to our

universe today you will be answering the

question why is the Sun set red the

lights that we see looks white but if

you look at it for a prism you can

actually see that the light is divided

up into many colors these are the colors

of the light spectrum and they are the

same colors that we see within a rainbow


we can see all of the colors of red

orange yellow blue and violet with the

exception of indigo with our eyes this

is very important because everything

that we can look at seems to have color

including the sunset each color that we

can see has a certain wavelength the

longer way vents are found in colors

such as red green yellow and orange and

the shorter wavelengths are in the blue

colors when light comes from the Sun to

the earth it comes in a straight line

and this has all of the colors of the

spectrum and each color is traveling at

its own wavelength

Sun could be slow and some could be fast


by the time that light reaches the

atmosphere of Earth it may encounter

water molecules dust or ice since the

light waves are incredibly small and I

mean smaller than one millionth of a

meter the light waves will interact with

even the tiniest gas molecules in the

air then they begin to bounce off the

parts course and this bouncing process

is called scattering and where they go

depends on how large the molecule was

compared to the wavelength size and

small particles compared to their

wavelength will scratch a blue light

more strongly than red light since the

Earth's atmosphere is mainly made up of

oxygen and nitrogen the Blues will

scatter sunlight in more directions than

the red and this creates the blue sky

that we see the red light waves have the

least amount of scattering and this is

due to the interaction with the gas

molecules so when you see a sunrise or a

sunset the sunlight is actually

travelling in a longer path through the

atmosphere and then finally to your eyes

where you can see it the blue light has

almost been completely removed but that

still leaves the red and yellow light

this is why when you see a sunset you're

actually seeing the colors of reds

oranges and yellows


and if there are any clouds in the sky

they will reflect these colors the

colors are being reflected from the

water and the ice particles in the

clouds and the molecules also absorb the

wavelength colors as well so when you

look up at a sunset you just realized

that there's no more blue left and the

Sun has to go for a lot of atmosphere to

actually show off the new colors of red

orange and yellow there are actually a

lot more colors but humans can't

actually see them there are specialized

equipment that scientists use to

actually see these colors and these help

scientists in various scientific studies

so in conclusion you can probably say

that the sky is not blue or red you can

actually say it's white until it

actually hits something within the

atmosphere that changes its color so I

hope that's given you a great insight

into why the sky is red or orange or

yellow when the Sun rises or sets and

also I've done another video on this

channel of why the sky is blue

that explains a little bit more on the

Rayleigh scattering and as always if
