The index of the refraction is 0.898 and the index of the refraction is less than one which is unreasonable because the speed of the light can't be more than c.
<h3>What is refraction?</h3>
The phenomenon bending of a wave as it crosses from one medium to another is said to be refraction. The difference in density is the cause of the bending.
Refraction is a term that is used to describe the phenomenon of refraction."The change in direction of a wave traveling through one medium to another is known as refraction."
From the Snell's law:
nsinФ = n'sin∅
We have n' = 1.33, ∅ = 10.0°, Ф = 14.9°
nsin110.0° = 1.33×sin14.9°
n = 0.898
Because the speed of light cannot be greater than c, the index of refraction is less than one, which is illogical.
It is illogical to assume that the angle of refraction is excessively large in relation to the angle of incidence.
Thus, the index of the refraction is 0.898 and the index of the refraction is less than one which is unreasonable because the speed of the light can't be more than c.

From the information given, Dairon already had a string that is 4 7/8 inches long.
We first write or simplify 3/8 and 4 7/8 in their decimal fraction forms.
3/8 is written as 0.375 and 4 7/8 is written as 4.875
We can now find out how many pieces he cut from the string (that was 4 7/8 inches), so:
4.875 ÷ 0.375 = 13
So he got 13 pieces of string. He wants 20 pieces, so;
20 -13 = 7
Therefore he will need 7 more strings .
