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.
E=h(new) where new is like a frquency component so we can say power & frequency are directly praportion to each.
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
0.0000000063
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.
The nth root of a number is the same as the number raised to the power 1/n. Thus sqrt(73) = 731/2 or cuberoot(95) = 951/3
To find the refractive index of a lens using a lensometer (or lens clock), place the lens in the machine with its convex side facing up. Look through the eyepiece and focus until the crosshairs are sharp. Take note of the position of the index line on the scale. Then, flip the lens and repeat the process. The refractive index can be calculated using the formula: Refractive index = (n2 - n1) / (1 - (t * (n2 - n1))) where n1 is the refractive index of air, n2 is the refractive index of the lens material, and t is the thickness of the lens.
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.
The lens will have a decrease in power when immersed in water due to the change in refractive index between the lens material and water. This change in the medium will alter the path of light through the lens and affect its ability to converge or diverge light.
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.
No relation is there power factor is a unit less quantity.
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.
Both are same
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.
