This is due to the phenomenon of refraction. When the rays of light from the coin travel from denser medium to rarer medium, the refracted rays bend away from the normal. The point from which the refracted rays appear to come gives the apparent position of the coin. Since the rays appear to come from a point above the Coin, it appears to be raised.

Why does a coin placed in a basin filled with water appear to be nearer the surface of the water?
because it is refracted.
Why does the coin placed at the bottom of the container appers to be raised when the container is filled slowly with water?
it is because the view we are seeing the coin is from rarer to denser that is from air to water so the refractive index differs so the view we so the coin at the bottom of the cointer appears to be raised
Why a coin placed at the bottom of a beaker containing water appears raised?
It is an optical illusion due to the fact that water is more dense than air and so slows the speed of light. When light travels from a less dense to a more dense material, it slows down and 'bends'.
When a coin is placed in water is it possible to pick up the coin when your eyes slide above water?
It is not possible.
Why does the coin appear to be nearer the surface of water?
due to refraction of light
Why does a coin appear bigger in size when immersed in water?
refraction (beams on light bend in the water)
Why does a coin in water seem raised to us?
It's an optical illusion created by the bending of light though the water.
How do you measure the volume of a 20cent coin?
Coins are not cylinders. The rim of the coin is sometimes raised, as well there are depressions and peaks from the design of the coin. You should use a specific gravity test with water and a scale.
What coin does the pygmy glider appear?
The pygmy glider does not appear on any coin. When Australia still had one cent coins, the feathertail glider appeared on this coin.
What is a Relief coin?
The relief on the coin is the raised pattern. Artists design the coin to be minted. They usually use a raised relief of a ruler, past ruler, symbol for the country, significant building, animal or flower.
Why the coin is bigger in water?
Because the light travels slower in water, therefore the light has to hit the surface area before reaching the coin, therefore it looks larger because the light if reflecting off the container walls and the light is hitting the coin and making it appear larger.
A cooper coin is placed so its touching a brass coin how will the heat flow?
heat will flow from the copper coin to the brass coin.
