Why does the coin appear to be nearer the surface of water?
When a coin is placed in water, light rays travel from water to air and get refracted. This refraction makes the coin appear to be nearer the surface of the water than it actually is. This is due to the change in speed of light as it moves from water to air, causing the coin to appear to be at a different position than its actual physical location.
Why does a coin appear to be raised in a glass of water?
When light passes from air to water, it refracts due to the change in density. This refraction causes the image of the coin to appear shifted, making it seem like the coin is raised when it's actually at the bottom of the glass.
Why the coin was seen when water is poured into the transparent cup?
When water is poured into a transparent cup with a coin at the bottom, the light gets refracted as it passes through the water and into the air, causing the coin to appear raised and no longer hidden by the water. This phenomenon is called refraction and it makes the coin visible even though it's at the bottom of the cup.
Does a coin sink faster in pure water than it does in sea water?
Yes, a coin does sink slightly faster in pure water than it does in sea water. The dissolved salts in sea water make the water denser, and as a result, objects immersed in sea water will experience greater buoyancy than they do in fresh water.
Why can you see the coin once water has been added to the cup?
When water is added to the cup, it refracts light in a way that causes the coin to appear shifted from its original position due to the bending of light rays. This phenomenon is called refraction. As a result, the coin becomes visible even though it is actually submerged below the water's surface.
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.

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 a coin appear raised when placed in a water tank?
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.

If a coin has a hole cut in it does the hole get bigger or smaller or stay the same when the coin is heated?
It gets bigger
Why the coin was seen when water was poured into a cup?
When water is poured into a cup containing a coin, the coin becomes visible due to the change in light refraction caused by the water. The water has a different refractive index than air, bending the light rays as they pass through the water. This optical effect can make the coin appear clearer and more distinct against the background of the water. Additionally, the contrast between the coin and the water enhances visibility, making it more noticeable.

Yes, a coin does sink slightly faster in pure water than it does in sea water. The dissolved salts in sea water make the water denser, and as a result, objects immersed in sea water will experience greater buoyancy than they do in fresh water.
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.
Why is a 2p coin bigger than a 1 coin?
That makes it easier to distinguish them.
