What are the alternatives?
A. Less than 0,
B. 0
C. between 0 and 1,
D 1.
A base less than 0 runs into all sorts of difficulties with fractional powers, such as square roots. Best avoided until you are an expert in complex numbers.
The Base of 0 and 1 are not particularly helpful. 0 to any positive exponent is 0 and to any negative exponent is undefined. 1 is not much better, since 1 raised to any power is 1 and that would not take you very far.
The base could be between 0 and 1, but that would be the same as using its reciprocal as the base and switching the signs on the exponents. It is intuitively simpler to have the base greater than 1 so that the bigger the power, the bigger the number.
So, although C is possible, it has not advantage over using a base greater than 1.

What is true of an index it must be larger than a 100?
No, it does not. It the quantity being measured is less than it was in the base period, ten the index will be less than 100.No, it does not. It the quantity being measured is less than it was in the base period, ten the index will be less than 100.No, it does not. It the quantity being measured is less than it was in the base period, ten the index will be less than 100.No, it does not. It the quantity being measured is less than it was in the base period, ten the index will be less than 100.
Can the base period of an index number be less than 100?
no
Why the index of refraction is greater than to one?
It is because the index is related to the velocity of light in air (ideally vacuum) and the medium in question. Since the velocity of light in vacuum is greater than it can be in any other media, the index of refraction of these other media relative to the vacuum is greater than 1.However, if you studied light travelling through glass and then water, the index of refraction between those two would be 0.89 (approx).
Which sign is greater or less than?
greater than > less than < The small end points to the smaller value.
Why is the index of refraction always greater than 1?
It is not, so the question is based on a fundamental misunderstanding.
