→ Rarer medium is Air . And, The denser medium is diamond. Because, light is travelling from rarer medium to denser medium . ▶ The refractive index of diamond is 2.42.
Is Diamond a denser medium?
When we say refractive index of diamond is 2.42, it means light is travelling from rarer to denser medium, and speed of light in air (vacuum) is 2.42 times the speed of light in diamond.
Is Diamond rarer than glass?
The refractive index of diamond(2.42) is much greater than that of glass(1.5). The large refractive index results in small critical angle for diamond i.e. about 240. … Thus the diamond shines.
Which is rarer and denser medium?
A medium in which speed of light is more is known as optically rarer medium and a medium in which speed of light is less is said to be optically denser medium. For example in air and water, air is raer and water is a denser medium.
Is Diamond rarer than air?
Rarer medium : The speed of light is more in air than in diamond.
Is air denser than diamond?
The new form of diamond has a very low density similar to that of the precursor of around 40 milligrams per cubic centimeter, which is only about 40 times denser than air.
What is the critical angle of diamond?
The critical angle for a diamond-to-air surface is only 24.4º, and so when light enters a diamond, it has trouble getting back out. (See Figure 7.) Although light freely enters the diamond, it can exit only if it makes an angle less than 24.4º.
Why do we use refractive index of diamond?
In this case we are talking about the measure of the speed of light as it travels through diamond compared to speed of light through air. Diamonds refractive index is a measurement of 2.417. This means that light travels through a diamond 2.417 slower than it travels through air.
Which has higher refractive index than diamond?
There are some gems such as Cuprite that has a very high refractive index of 2.849, invariably higher than diamond (2.417 – 2.419). The other two are Hematite (2.940-3.220) and Cinnabar (2.905-3.256).
Is Diamond optically denser than glass?
Yes, Diamond is optically denser than glass. Speed of light in diamond is 125000 km/s.
Is air rarer a medium?
A medium is rarer when the speed of light increases when light travels through that medium. Speed of light in air is more than speed of light in glass, which means air is optically rarer than glass.
What do you mean by optically rarer medium?
An optically denser medium is one that slows down the incident wave, an optical rarer medium is one that causes the electromagnetic wave to pass through faster than in the medium it moved through before. … As a wave passes from an optically rarer to an optically denser medium the ray bends more towards the normal.
What is the meaning of rarer medium?
RARER MEDIUM MEANS AN OBJECT WITH LESS PARTICLES… eg: AIR IS RARER THAN GLASS, WHILE GLASS IS DENSER THAN AIR…
Can you break a diamond with a hammer?
As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. … This makes the diamond incredibly hard and is why it is able to scratch any other material.
What’s harder than diamond?
Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.
Is Diamond heavier than steel?
Are Diamonds Stronger than Steel? … Steel is also denser than diamonds because each molecule weighs much more than a carbon atom alone. A diamond’s smoothness allows it to easier to resist wear and tear for tools such as diamond tipped drills.
