WebApr 5, 2024 · The speed of light in water is more than its speed in a medium of glass. This suggests that out of the two mediums, glass and water, glass is the optically denser one. So we can say that water is optically rarer than glass. The refractive index of water is known to be n w = 1 ⋅ 33 . The refractive index of glass is known to be n g = 1 ⋅ 5 . Web1) Denser mediums are better insulators. 2) Denser mediums are also better at being barriers. 3) Both denser and rarer media are good insulators against the cold and heat, depending on what the material is made of. 4) Denser media or obstacles can completely block sound from traveling from one place to another.

WebLight travels from a rarer medium to a denser medium (from air to optical fiber). Therefore, the refracted ray bends towards the normal. The angle of refraction – We will take air as medium 1 and optical fibre as medium 2. Therefore, n 1 = 1, n 2 = 1, and θ 1 = 22 o.
