The refractive index and refractive power are both directly proportional because
due to power the distance is decrease or increase if power increases or decreases
and to refractive index the bending of light occurs in towards or away. Bending of
light ray and distance of light ray are directly proportional so refractive index and
power are directly proportional.

Answer #2:
They have very little connection, except that the same big word appears in both terms.
Refractive index of a substance is the ratio of the speed of light in vacuum to the
speed of light in that substance.
Refractive power of an optical device, like a lens, does naturally depend somewhat
on the refractive index of the material used to make the lens, but it's got much
more to do with the shape of the lens ... the curvature of its surfaces etc.
You can make lenses with a wide range of different refractive powers, all out of
the same kind of glass with the same refractive index. And you can construct
lenses that all have the same refractive power out of many many different
substances with different refractive indexes, like crown glass, flint glass, plastic,
jello etc. So in that sense, the two are completely unrelated.

What are the units of dispersive power?
Dispersive power is a dimensionless quantity, indicating the ability of a medium to separate different wavelengths of light. It is often expressed as the ratio of the difference in refractive indices of two wavelengths to the refractive index of a third wavelength. Since it is a ratio of refractive indices, which are also dimensionless, dispersive power has no units.
What is relation in between power and frequency?
E=h(new) where new is like a frquency component so we can say power & frequency are directly praportion to each.
What does index mean in maths terms?
index is the same as power The index of a number say how many times you have to use the number in a multiplictaion. e.g; 2 10 = 10*10=100
What is 6300 times 10 to the power of -12 in standard index form?
0.0000000063
Is index the same as squared?
No. The power 2, which denotes squared, is one of an infinite number of possible values for the index. Indices (or powers) can be negative, fractional, irrational or even complex.
How do you use the lensometer or lens clock for finding the refractive index of a lens?
The formula for calculating a lens' refractive power is as follows:n = (D * R) + 1, where n = refractive power, D = optical power in diopter, and R = lens curvature radius.A lens clock will give you an estimated optical power, d and from there you can work out the curvature radius by using the formula:R = (0.53)/d.A lensometer will give you the actual optical power, D.Input the R and D into the first formula and you will get the lens' refractive index, n.
What is the minimum deviation of prism whose refractive index is three to the power half?
The minimum deviation of a prism can be calculated using the formula: δ = (n - 1)A, where δ is the minimum deviation, n is the refractive index of the prism, and A is the angle of the prism. If the refractive index of the prism is three to the power of half, or √3, and the value of A is known, the minimum deviation can be calculated using the formula.
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)
What would be focal length and power of a glass when it is dipped in liquid of refractive index equal to glass?
Lenses operate on having another index than the immediate surrounding. Sink a lens in a media with the same index and it won't work. It'll be like it's all glass.
What is the relation between power factor and frequency for purpose of parallel operation of alternator?
No relation is there power factor is a unit less quantity.
What is the relation between the size of the resistor and its value?
There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.
What is relation between resistance power and susceptibility?
Both are same
How can the magnifying power of a simple microscope be increased?
The magnifying power of a simple microscope can be increased by using a lens with a shorter focal length, increasing the distance between the lens and the object being viewed, and adjusting the eye position to be closer to the lens. Additionally, using a lens with a higher refractive index can also help increase magnification.
What is the Relation between power factor and slip?
inversely proportional relationship
What is Relation between loss angle and Power factor?
Power factor = cos (angle)PF=cos @
