What causes objects to look different in water?

An object seen in the water will usually appear to be at a different depth than it actually is, due to the refraction of light rays as they travel from the water into the air. If the angle of the beam is increased even farther, the light will refract with increasing proportion to the entry angle.

Why does an object feel lighter when suspended in water?

Any object immersed into the water or any liquid it experiences an upward force which is equal to the weight of the fluid displaces by it . This is called buoyant force. so the object is lighter when it is inside the water than it is outside .

Why does a piece of stone appears lighter when it is in water?

Solution: In water, the stone experiences a buoyant force which counter balances the weight of the stone acting downward and this makes the stone lighter and thus easier to lift the stone in water.

Is steel lighter in water?

A little bit, yes. They would feel lighter by exactly the weight of the water they displace. The density of iron is 7874 kg/m³. Compare that to the density of water, which is “only” 1000 kg/m³.

Why do things feel lighter in the ocean?

They seem to feel lighter, though, because of buoyancy. Archemedes’s principle states that the force pushing on an object under water, is equal to the mass of the water it has pushed out of the way. So things apear lighter because the water is actually helping to push it up. Posted on November 28, 2014 at 11:53 am

Why do objects look bigger in water than air?

$$ Since air has an index of refraction of essentially 1 and water has an index of refraction of 1.33 the angle from which the rays of light reach your eyes is larger than the angle they would in air. This makes the angular size larger to your eyes which makes the object look larger relative to how they would look in air.

What happens to light when it travels from air to water?

When light travels from air into water, it will change its speed and its direction. As light travels into a denser medium (water), the light ray will ‘bend’ toward the normal. When it goes back into the less dense medium (air), it will bend back through the same angle as when it came in.

Why does lifting a heavy weight under water make it lighter?

Because of the buoyancy effects of water. The weight of a heavy weight (any solid denser than water) you are lifting while the weight is fully submerged under the surface is reduced by the weight of water displaced.
