Why does a coin appear bigger in size when immersed in water?
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.
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 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 does a coin in water seem raised to us?
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.
What does the coin that lies submerged at the bottom part of water looks?
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.
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 bigger in size when immersed in water?

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.

Can copper coin float on water?
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.

When you get water how do you make it stay on a one pence coin?
To make water stay on a one pence coin, you can carefully place a drop of water on its surface using a dropper or the tip of your finger. The surface tension of the water helps it hold together and stay on the coin. Additionally, tilting the coin slightly can help create a dome shape that allows the water to remain without spilling over.
Why does water on a coin bubble up onto the coin without running over the edge?
Water forms a convex shape on a coin due to surface tension, which is the cohesive force between water molecules. This tension allows the water to "pull" itself into a dome shape, minimizing contact with the coin's surface and resisting the force of gravity that would cause it to spill over the edge. Additionally, the coin's smooth surface enhances this effect by reducing the adhesion of water to the coin, further promoting the formation of droplets rather than a flat puddle.
When you dive for a coin at the bottom of a swimming pool the coin is not exactly where it appeared to be?
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.
If you are picking up a coin on the bottom of the pool can you just reach for where the coin appears to be why or why not?
No, you cannot just reach for where the coin appears to be because of the refraction of light in water. When light passes from air into water, it bends, making objects appear higher and closer to the surface than they actually are. This optical illusion means that if you reach directly for the coin as it appears, your hand will likely miss it. You need to adjust your aim to account for this distortion.
