due to refraction of light
When a coin is immersed in water, the water refracts the light that passes through it. This refraction makes the coin appear bigger and closer to the surface of the water than it actually is. It's an optical illusion caused by the way light travels through different mediums.
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.
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.
This phenomenon is known as refraction, where light passing through water changes speed and direction, causing the coin to appear raised due to the bending of light rays. Our brain interprets this distorted image as the coin being closer to the surface than it actually is.
As the coin submerged in water and kept at the bottom of the vessel and if it is looked right from the top then it will appear to be lifted up by a small distance such that the actual depth / apparent depth = refractive index of water. If suppose the actual height of level of water is 12 cm then the coim will be shifted up by 3 cm. So the apparent depth will be 9 cm. Hence refractive index of water = 12/9 = 4/3 = 1.333.
because it is refracted.
When a coin is immersed in water, the water refracts the light that passes through it. This refraction makes the coin appear bigger and closer to the surface of the water than it actually is. It's an optical illusion caused by the way light travels through different mediums.
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.
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.
A coin can float on the water under a couple of circumstances. The most obvious is if it is made of a material lighter than water. And the second is if it is broad enough that it can be laid on the surface (carefully) and in such a way that the surface tension is not broken.

It's not where it appears to be because the sun's rays are reflecting off of the water surface, and the water surface are bending the rays, so it looks like the coin is somewhere else.
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.

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.
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.
