Optical illusion phenomena || Refraction of light • #experiment #science #subscribers #opticalillusion • This is a magic of science!! • Time stamp : • 00:00 magic of science • 00:08 How to disappear the glass • 00:36 Lateral displacement effect • 00:58 water as a lens • 01:52 Function of gelly beads • 2:30 Basic structure of gelly beads • Can something disappear without using any trick? • It’s yessssss!!! Let’s find out ---- • Look,I've placed a smaller glass inside a larger one. Now, as I pour oil inside the smaller glass, you can see that it disappears completely! • How did this happen???? • Place a test tube inside the smaller one. Follow the changes very carefully. • See the test tube is also vanished as well. It’s Lateral displacement. • Let’s understand what happens during this demonstration. • We are using here soybean oil of refractive index = 1.47, and the RI of glass used here is = 1.52 ; As these two are optically similar, so no light is bending making everything disappear at the border between the oil and glass. • Isn’t it fascinating!!! • Time stamp : • Related video : • A natural phenomenon || lateral inver... • ** Let’s see what Refractive Index actually mean. • Refraction occurs when light changes speed and direction as it moves from one substance to another. The bending of light at the interface between two substances is called refraction. Different substances bend light differently, which is known as a substance's refractive index. • If we perform the same experiment using water, we can see that the glass is not fully vanished rather it’s magnified. That means water is behaved here as a lens. We have already discussed the fact in another video, you can check the description box, the link is added there. • Another fact is happening here. The refractive index of water is 1.33, which is significantly lower than that of glass (1.52); whereas the refractive index of oil is = 1.47. Thus the inner glass is visible in water. • Now, this is where it gets interesting. You'll need some water crystal gell or commonly called gelly beads. Now a days children are fascinating about Orbeez. These are small, colorful, gel-like beads that grow when soaked in water. The tiny, super-absorbent polymer balls can expand up to 400 times their original size when they come into contact with water. • The refractive index of gelly beads is similar to the refractive index of water. This makes the beads nearly invisible because light rays don't bend when traveling between two substances with the same refractive index. • Orbeez are made of a special type of superabsorbent polymer (SAP), primarily composed of cross-linked sodium polyacrylate. This polyacrylate is formed from acrylate compounds, long-chain molecules consisting of repeating units known as monomers. Sodium polyacrylate (NaPA), also named as poly (sodium prop-2-enoate), presents the molecular formula (C 3 H 3 NaO 2 ) n . • This structure allows Sodium polyacrylate (NaPA to absorb and retain large amount of water. • Hope you all have enjoyed the video. Thanks for tuning in.
