Answer:
The index of refraction for Medium 2 would be 1.25
Step-by-step explanation:
We have the following data:
Speed of light in Medium 1 = V₁
Speed of light in Medium 2 = V₂
The speed of Light in Medium 2 is related to speed of light in Medium 1 as:
V₂ = 0.8 V₁
Moreover, it is given that Medium 1 is air with index of refraction equal to 1. i.e.
n₁ = 1
We need to find the index of refraction for medium 2. Lets name it is as n₂.
Snell's law related the above mentioned 4 quantities by following relation:
The ratio of indices of refraction of 2 mediums is equivalent to the reciprocal of ratio of phase velocities in those 2 mediums. Mathematically, this can be written as:

Substituting the values we have gives us:

This means, the index of refraction for Medium 2 would be 1.25
Answer:
1 & -1
Step-by-step explanation:
f(x) = g(x)
Find the inputs for which outputs are equal
Both outputs are 1 when x = -1
Both outputs are -7 when x = 1
Answer:
<h3>Domain [
-3 , ∞ ]</h3>
Step-by-step explanation:
Domain is the set of all inputs for which the given function is defined.
graphically it represents the shadow of the graph taken on the x axis from above and below the x axis
Here is the shadow will be formed from -3 till +∞, hence we have our domain as [-3 , ∞ ]
Add 3 and 12 , cancel -2 y+2y and and add 14 and 14
3x-2y=14
12x+2y=14
15x=28
Divide both sides by 15
X=28/15
3x 28/15 -2y=14
Y=-21/5
(X,y)=28/15, -21/5
3x 28/15 -2x(-21/5)=12x 28/15 +2x(-21/5)=14
14=14=14
(x, y)=(28/15, -21/5) is the answer
