Why do objects underwater seem closer to the surface than they are?

When an object is submerged in water (higher density medium) they seem shallower if you are looking at it from air (lower density medium). This is because the light rays slow down as they move from a medium of lower density (air) to a medium of higher density (water) and tend to refract (bend) towards the normal (surface of the water) hence the seem shallower (closer) than they actually are!

∙ 9y agoWater appears less deep than it really is because of how much light surrounds it. The water in a pool, for example, looks shallower than it really is because light is being refracted and angled away from the pool, altering your perception of the water's depth.

∙ 11y agoThe objects underwater seem closer to the surface than they are because of the angle of refraction. The angle of refraction is the angle of the light ray passing through the boundary between two materials, for example glass and air. The angle of refraction is measured between the refracted rays and the normal.

Why an object underwater feels lighter than it is in air?
There is a force called upthrust coming from the water. this pushes objects upwards, making the resultant force lower, which means they seem to weigh less.
What is the effect of objects in a painting duller than others?
The duller objects will seem farther away.
Why an object underwater feels lighter than when it is in air?

Were else can you find gravity but earth?
Yes. Gravity exists everywhere in the universe as all objects have a gravitational pull. Objects in space do not seem weightless because there is no gravity. Rather they seem weightless because they are in freefall.
If a person is in front of a smooth surface from which a sound is reflected the person would hear a sound that?
The answer should seem to come from behind the surface.
Why do objects underwater seem to be bigger and nearer than in reality?
because of refraction
Why does the moon seem larger than other objects in the sky?
It is closer than most of those other objects.
According to linear perspective people and objects appear to get?
They appear to seem smaller the further away they are,and bigger the closer they get.
What is the advantage to having mirrors that say objects may appear closer than they seem?
On a mirrors that say "objects may appear closer than they seem" have a greater field of view then a conventional flat mirror. If you look at it very closly you will notice it is slightly convexed, much like a fisheye lens.

Why do sounds seem louder when closer?
Sounds are louder when they are closer, because the sound is closer to your ears.
What is the effect of making objects in a painting duller than others?
The duller objects will seem farther away.
Why does s not gravity pull fish to the surface?
gravity is a force that pulls objects towards one another. if one of those objects is very massive compared to the other, as in a person on the surface of the earth, it can seem like gravity is only acting in one direction (it is still acting both ways, but the earth force of gravity exerted on the earth by a person is infinitesimally small.) In the case of fish in the ocean, it might seem like they should be attracted to the surface of the earth, because that's what objects on the surface are attracted to, but really all objects are attracted to the center of the earth, because that is its center of gravity - so there is no reason the fish should be pulled to the surface. On the other hand, the reason fish don't fall to the bottom of the ocean is due in great part to the force of buoyancy.
Why does the moon seem closer sometimes?
because theres a time when the moon is closer to the earth called perigee

Why do objects seem to be lighter in water than in air?
Objects are more buoyant in water than in air.
When you observe objects in space why does it seem that the objects you observe are moving across the sky?
Because the earth is rotating.
