The minimum index of refraction for any substance is 1.000. That is the value for a vacuum. As the substance becomes more optically dense, the value of the index of refraction will increase.
The index of refraction (n) is defined in terms of the speeds of
light (c) in a vacuum (3.00x10^8 m/s) and in the substance (some
lower speed).
n = c(vac) / c(substance)
so, the value of refractive index should be greater than or equal to 1

The figure shows the vertical interface between two transparent
materials with different indices of refraction. You do not know the
exact value of
for each material, but you are told that total internal reflection
is possible for light rays incident on the interface from the right
side.

One way to find prime numbers less than n is to treat them as array indices. Mark each position as True initially, assuming that all numbers are prime. Then, starting with index 2, mark all multiples of 2 (greater than 2) as not prime (False). Repeat this for multiples of 3, then multples of 4, etc. When the algorithm terminates, only prime indices will still be True; everything else will be False. The following function takes an integer n as...
