The refractive index of a certain material increases with its density. The refractive index of ice is less because it has a lower density than liquid water.

Does freshwater have a lower density than salt water?
Yes, fresh water has a slightly lower density than salt water.
Which has a lower boiling point butane or water?
benzene has lower boiling point than water
Describes a solution with a pH lower than the pH of distilled water?
Water is neutral (pH 7). Lower numbers than 7 are acids- the lower the number, the stronger the acid.
Why does normal water have lower sodium chloride levels than salt water?
Because sodium chloride is salt! Obviously normal water has lower salt levels than salt water.
How does fresh water freezes faster than salt water?
When water has a substance dissolved in it, it freezes at a lower temperature. Salt water has salt dissolved in the water, so it freezes at a lower temperature than fresh water.
What is the Nature of a convex lens immersed in a liquid with refractive index greater than of glass?
Usually a convex lens made up a material with higher refractive index would act as a converging device when kept in a medium having lower refractive index such as air. But when it is kept in a liquid as said with higher refractive index then convex lens would become as a concave lens. Now it would diverge the rays entering through it right from the liquid with higher refractive index.
Can light moves more slowly than air in the water?
Light in water is 1.333 times slower than light in the air. The reason is that the light is transformed into potential energy in the electrons and exits again as a light particle, so in air it performs the transformation less than in water. Air has a refractive index which is close to a vacuum, refractive index 1.000, whereas in water the refractive index is 1.333. The index is used when calculating the many different effects substances have on light. The index itself changes, depending on the wave length (ultraviolet, infrared, etc.)
Why do things in a pool appear closer than they actually are?
The refractive index of air (n=1.00) is less than the refractive index of water (1.33) so when light rays transmit through the water the rays are refracted and produce a "virtual image" making the object appear closer.
A lens of glass is immersed in water. What will happen to its power?
The power of a lens depends on the differences in the refractive indices of the environment and the lens material. A glass lens immersed in water will loose power (a positive lens will focus at a greater distance). (This is for normal glass with refractive index greater than water - there could be glasses with refractive index less than water in which case the lens would gain power)
Why air bubble in a glass slab have silvery look?
refractive index of glass is higher than refractive index of glass slab OR density of air is less than density of glass
Light travels faster through water n 1 33 than it does through glass n equals 1 5?
The speed of light in any medium is given by its speed of light in vacuum divided by the refractive index of the medium and so light will travel faster in water than in glass since refractive index of glass is greater than that of water.
Is this true or false that light moves slower through water than through air?
Yes it is true. If c is the speed of light in air then in water it will be 3/4 of c Hence refractive index of water = speed of light in air/speed of light in water So refractive index = 4/3 = 1.333
How does the speed of light in glass compare to the speed of light in a vacuum?
It will depend on the type of glass, and something called its refractive index. All materials have a refractive index which will effect the speed of the light through it. The speed of light through a vacuum is 3.0x10^8 m/s, and a material such as glass will be lower than this.
Why core refractive index should be greater than cladding?
yah! i think.....
Why refractive index of core is lower than cladding in optlical fiber?
because in the fiber optics the transmission of the light waves are through core and cladding is to cover the core
What do people learn when they see that a pencil is bent in water?
Usually nothing, but if they are paying attention they might learn that water has a different refractive index than air or glass.
What is the index of refraction of sugar?
Crystaline sugar (sucrose) has a refractive index of around 1.56. Sugar solutions can have refractive indices greater than this. Note, that the refractive index of a substance can even be determined for opaque substances. This is because the RI also determines reflective properties. So by measuring the amount of light reflected by light shining on a polished sample at a given angle, a refractive index can in principle be obtained.
