If the speed of light through material Z is

2.5×10^8 m/s, what is this material’s index of
refraction? The speed of light in a vacuum is
3 × 10^8 m/s.

(3x10^8)/x = 2.5 x 10^8

x= 1.2

Well, if the speed of light in a vacuum is 3 × 10^8 m/s and the speed of light through material Z is 2.5 × 10^8 m/s, then it seems like material Z is a bit of a slowpoke when it comes to letting light pass through.

To find the index of refraction, we can use the formula:

Index of refraction = speed of light in vacuum / speed of light in material

So in this case, let's plug in the numbers:

Index of refraction = (3 × 10^8 m/s) / (2.5 × 10^8 m/s)

Math, math, math...

Index of refraction ≈ 1.2

So the index of refraction for material Z is approximately 1.2. It's not exactly a speed demon, but hey, we all have our own pace, right?

To find the index of refraction of material Z, we can use the formula:

Index of refraction (n) = Speed of light in vacuum (c) / Speed of light in material (v)

Given:
Speed of light in vacuum (c) = 3 × 10^8 m/s
Speed of light in material Z (v) = 2.5 × 10^8 m/s

Substituting these values into the formula, we have:

Index of refraction (n) = (3 × 10^8 m/s) / (2.5 × 10^8 m/s)

Calculating this expression, we get:

Index of refraction (n) = 1.2

Therefore, the index of refraction of material Z is 1.2.

To find the index of refraction (n) of material Z, you can use the formula:

n = c/v,

where "c" is the speed of light in a vacuum (3 × 10^8 m/s) and "v" is the speed of light through material Z (2.5 × 10^8 m/s).

Substituting the given values into the formula, we have:

n = (3 × 10^8 m/s) / (2.5 × 10^8 m/s).

Now, let's simplify this expression:

n = 1.2.

So, the index of refraction of material Z is approximately 1.2.

n=c/v

where
n =the index of refraction
c =the speed of light in vacuum
v =the speed of light in a medium

find n
