Answer:

C) Index of refraction

Explanation:

Index of refraction also known as refractive index is defined as speed of light in a vacuum divided by the speed of light in a given material.

The formula for Index of refraction is:

n = c ÷ v

where n represents Index of refraction,

c represents speed of light in a vacuum,

v represents speed of light in a given material.

The speed and direction of light changes when it moves from one medium to another. The change in direction is basically called refraction.

in positive numbers less than 1, the zeros between the decimal point and a non-zero number are _______ significant?
DedPeter [7]

Answer:

Explanation:

If a number of less than 1, then the number has a decimal point like

0.085, 0.008 e.t.c.

The zeros before the none zero digit are insignificant. The significant figure is 8 and 5.

But if there a zero between the none zero e.g. 0.0087056

Here the zero between 7 and 5 is significant, then the significant numbers are 8,7,0,5,6

But if the zero is not in between the none zero digit, then the zero is insignificant

E.g 0.05800

The last two zero is insignificant, the significant number is 5 and 8

So, If a positive numbers less than 1, the zeros between the decimal point and a non-zero number are NOT significant.
