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.

#SPJ1
Original cube side length is s = 4 inches, so the vol. is 4^3 in^3, or 64 in^3 = s^3.
If we double the original side length, we get S = 2s, and the new volume
is S^3 = (2s)^3 = 8s^3 = 8(64 in^3) = 512 in^3.
Answer: the new cube has a volume 8 times greater than the original cube has.
The answer is Theta = 7/5
Hope this would do... :)
Answer:
Step-by-step explanation:
Let's call the number x. The statement "...2 times a number" if the number is x looks like this:
2x
"8 less than" that looks like this:
... - 8
Putting the whole thing together:
2x - 8
Half the area: 2 by 8
Quarter of the area: 2 by 4
