How far is the horizon from the shore?

Question

How far is the horizon from the shore?

Answer 1

Roughly eleven miles, depending on elevation, etc.

Answer 2

if i remember correctly the earth curves at about i foot per mile therefore you height determines how far you can see to the horizon. a 6 foot tall man can see 6 miles. my recollection is hazy on this. i have been checking and it seems the curve is 8 inches per mile which means our six footer can see 9 miles rather than six. sorry for the mistake.

Answer 3

Depends upon your height and not on the shore. If you are almost six feet high, horizon is 3.4 miles away.

Answer 4

The horizon is as far as you can see.

Answer 5

Approximately 3 miles for a 6 foot person standing at sea level.

Answer 6

The formula for distance from the viewpoint to the horizon on any sphere is

d = square root of (2Rh) + (h squared)

(I wasn’t sure if superscripts would show up)

Where R is the radius (of the Earth or any sphere)

h is the height of observer

d is the distance from observer to horizon

(note: both R and h in this equation must be given in the same units)

All calculations depend on the water's surface being completely smooth, no waves! Sounds like a very calm day.

Using this a person with his eye level at 5 feet 8 inches above water could see the horizon 2.92 miles away.

Metric: 1.73 meters and 4,695.06 meters.

If you are standing on a ship 30 feet above the water line, the horizon is 6.71 miles away.

Metric: 9.14 meters and 10,794.12 meters.

If you are standing on a hill 100 feet above the water, the horizon is 12.25 miles away.

Metric: 30.48 meters and 19,707.29 meters.
