When light passes from one medium to another with the same refractive index, there is no change in the speed of light, and the light does not bend or refract. This causes the light to pass through without changing direction, making the irregularly shaped glass appear invisible when immersed in the liquid of the same refractive index.
It's quite simple once you know the secret. He is walking across a plexiglas {perspex} platform that is set several inches below the water. It works because refractive index of plexiglas is close to of water, so that it becomes invisible once immersed.
The shape of the lens changes by becoming thicker or thinner, known as lens accommodation, to focus on objects. When focusing on a near object, the lens becomes thicker, and when focusing on a distant object, the lens becomes thinner. This process allows the lens to adjust its refractive power to bring objects into focus on the retina.
Refractive index of the medium is equated to 1/ sin C Here C is the critical angle. Diamond has high refractive index more than 2. So critical angle becomes very low. So for falling radiations at angles of incidence greater than this smaller value of critical angle, total internal reflection becomes possible.
Condensation is the process where water vapor in the air becomes liquid water when it comes into contact with a cool surface. It does not turn water from a visible to an invisible state; rather, it transforms water vapor into visible liquid water droplets, such as when you see water droplets form on a cold glass of water on a hot day.
The lens of the eye adjusts its shape to focus light rays onto the retina, allowing us to see both nearby and faraway objects clearly. When looking at objects up close, the lens becomes more rounded to increase its refractive power. For faraway objects, the lens flattens out to decrease its refractive power. This process is known as accommodation and enables us to have clear vision at various distances.
When immersed in oil, glass becomes nearly invisible due to a phenomenon called "refractive index matching." This occurs because the refractive index of glass closely matches that of oil, leading to minimal light reflection or refraction at the glass-oil interface. As a result, the glass appears to disappear when submerged in oil, making it difficult to see with the naked eye.
Because Glycerol and glass have the same refractive index. ie light is bent (refracted) by the same amount when the light travels from air to either the glass or the glycerol. Therefore when combined together you will only see the exterior substance (in this case glycerol) not what is hidden inside it. I believe there is a similar affect with diamonds in immersed in water ie. they disappear. This is also apparently a good way to check if a diamond is real.
a menstruation , because it becomes irregular which is portion then it stops which is fratiom so, it is irregular and stops .. the answer is menstruation ...

No, it is not, because its spelling does not change when you make it plural it just becomes pianos. Whereas mouse is and irregular noun, because its spelling does change when it becomes plural, as it becomes mice. Hope that helps.
Un: reverses the meaning of the base word, eg. "happy" becomes "unhappy" Re: indicates repetition or back, eg. "do" becomes "redo" Im: often signifies not or into, eg. "possible" becomes "impossible" In: denotes negation or lack, eg. "visible" becomes "invisible" Ir: negates words starting with 'r', eg. "regular" becomes "irregular" Il: negates adjectives starting with 'l', eg. "legal" becomes "illegal"

When a solid dissolves in a liquid and becomes invisible, it is said to have dissolved. This process results in the solid particles dispersing evenly throughout the liquid, creating a homogeneous mixture.
Invisible ink typically lasts for a few hours to a few days before it becomes visible, depending on the type of ink used and the conditions it is exposed to.
In Fairy Tail, Lucy turns invisible in Episode 11, titled "The Cursed Island." She becomes invisible after being hit by a mysterious green light.
Because they have a hard outer shell with a softer interior.
Yes, some irregular nouns change their vowel sound to form the plural. For example, "man" becomes "men" and "foot" becomes "feet."
