Example Question #41 : Snell's Law

Suppose that a ray of light passes from air into another medium. The light ray strikes the surface of the medium at an angle of $30^{o}$ with respect to the normal. If the light ray is refracted such that it bends $15^{o}$ with respect to the normal, what is the index of refraction of this medium?

Note: The index of refraction of air is .

Possible Answers:

1.12

1.33

1.69

1.50

1.93

Correct answer:

1.93

Explanation:

In this question, we're told that a ray of light is hitting a medium which causes it to undergo refraction. We're provided with each of the angles with respect to the normal, as well as the index of refraction of the first medium. We're asked to find the index of refraction for the second medium.

First and foremost, we'll need to use the equation for Snell's law.

$n_{1}sin(\Theta _{1})=n_{2}sin(\Theta _{2})$

If we treat $n_{1}$ as the index of refraction for air, we can then use $n_{2}$ as the index of refraction for our unknown medium. Then, we can rearrange the equation to isolate the $n_{2}$ variable.

$n_{2}=n_{1}\frac{sin(\Theta _{1})}{sin(\Theta _{2})}$

Now, we can plug in the values that we know to solve for our answer.

$n_{2}=1\frac{sin(30^{o})}{sin(15^{o})}=1.93$

1.52

1.11

Correct answer:

2.29

Explanation:

Using Snell's Law:

$n_1sin\theta_1=n_2sin\theta_2$

The index of refraction of a vacuum is unity, n=1

Plugging in values:

$1sin45^\circ=n_2sin18^\circ$

n_2=2.29
