This is what the angle would be using the height of the observer and the distance of three miles

Which part ?

1 inch off the ground or 5 feet up?

6 feet?

I'm tired gotta goto sleep

The angle that was labeled in the last pic

Ugh whatever ok

What height did you use?

This is the distance the object would disappear using 0.02 as the angle and 6ft as the height of the observer

I used 6 ft for both

Feel free to check the math

It's simple geometry

Cool.thanks ill look at it

Ok tell me what you think when you're done

So what r u saying?

According to the information provided, objects of the size specified would vanish fully at 299.96 feet instead of 3 miles

You must of done something wrong

You're welcome to find where I messed up

Think about what you are saying

I did

5 foot object doesnt disappear at 300 feet

It does at 3 miles

Now you're catching on

It would vanish to the naked eye

At 300 feet the bottom few inches prolly start disappearing

Without a telescope

5 feet isn't too big

I would imagine it'd be hard to see from that far away

The bottom starts disappearing, sure. But that's assuming you can see it without using a telescope

Thats what we are talking about just human vision limits

Ok hun

The angle of light going into the retina

In the back of the eye

Yep

K

Would you care to explain how the sail of a sailboat does not become unresolvable gradually when aided by a telescope then

It does

Or maybe why it doesn't appear to sink when viewed by the naked eye

It does

It doesn't

Sure it does
