it's not very noticeable, it supposedly happens
but there must be refraction whether it's flat or globe
here, an 8 hour long car drive
going pretty straight
you can see that objects in the horizon get closer
Refraction tends to bend down unless there are heat waves or humidity that can cause heavy miraging
what causes the refraction?
dielectric responses in materials/air
The standard refraction model basically mimics angular resolution
is the sun above or inside the atmosphere?
What causes refraction? A change in medium
from which medium to which medium?
it can be a continuously changing medium
Atmospheric particles bend the light similar to .. a process of drag
Sometimes the heat and wind can lift the image and wobble it
Hmmm 🤔
Kind like how a paper bag moves in the wind
Angular size and refraction can be entirely separated as two different concepts
i don't think refraction can explain how much the horizon moves
we are saying they're separate albert
I agree, thats why i dont believe in the globe
The horizon is a property of a perspective matrix closing into a vanishing point combined with minor refraction
The horizon is literally caused by your sharp angle to the surface
why does refraction have a limit?
and i think i do agree that usually the main effect of horizon is angular size
Because there is an angle where light is absorbed or reflected. Refraction is super tricky i dont even want to pretend i am an expert
However let me source a great video for you
there is total internal reflection but
i don't think that would put a limit on how much it can bend in the atmosphere
sure
There we go
That video delivers
i think i agree with most of it
like refraction being important on FE
Its important over water
right, for the more subtle effects
like over water
Over land... Dry areas.. things generaly are visible at distance but elevation is in question
