Why that the coin is disappaer in refractive index?
due to the process of refraction of light refraction is a process of bending of light when moving from one medium to other our eyes can view any object when the reflected light reaches the the human eye only thus similarly for any object the the reflected light is needed to see it but in this case where a certain amount of refracted rays some reflects back to our eyes.this gives the image of the coin but when the refraction is so high such that the reflected rays never reach our eyes and the coin disappear . note:do not confuse between the reflection and refraction
Why when you dive for a coin at the bottom of a pool the coin is not exactly where it appears to be?
When you dive for a coin at the bottom of a pool, the light refraction at the water-air interface causes the image of the coin to appear higher than its actual position. This bending of light makes the coin look like it's somewhere it's not, leading you to misjudge its location.
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 a coin kept in a vessel is not visible from edge but can be viewed by pouring water into the vessel?
When a coin is placed in a vessel, it is hidden from view due to the refraction of light as it passes through the water and hits the edge of the vessel. When water is poured into the vessel, the light refraction changes, making the coin visible from the edge by altering the path of light rays, essentially bending them so that the coin becomes visible.
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.
