## Introduction of Snell's Law Calculator

Welcome to the fascinating world of optics, where light bends, reflects, and illuminates our understanding of physics. Snell's law, which describes the fundamental way that light changes direction as it travels through various mediums, is essential to comprehending the fundamental behavior of light. We delve deeper into Snell's law and examine how Snell's law math might reveal its mysteries in this extensive guide.

## What is Snell's Law?

Snell's Law pertains to the relationship between the angles of incidence and refraction as light travels through various media and is named after the Dutch mathematician Willebrord Snellius. In mathematical terms, it is stated as:

Snell's Law describes the relationship between the angles of incidence and refraction when light passes through different mediums. It is expressed mathematically as:

$n_1 \sin(\theta_1) = n_2 \sin(\theta_2)$

Where:

• $$n_1$$ and $$n_2$$ are the refractive indices of the initial and final mediums, respectively.
• $$\theta_1$$ and $$\theta_2$$ are the angles of incidence and refraction, respectively.

This equation signifies that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for a given pair of media.

## Snell's Law Examples with Solutions

### Example 1:

Light travels from air ($$n_1 = 1$$) into water ($$n_2 = 1.33$$). If the angle of incidence is $$30^\circ$$, what is the angle of refraction?

The Snell's Law equation is:

$n_1 \sin(\theta_1) = n_2 \sin(\theta_2)$

Substituting the given values:

$1 \times \sin(30^\circ) = 1.33 \times \sin(\theta_2)$

Solving for $$\theta_2$$:

$\theta_2 = \arcsin\left(\frac{1}{1.33} \times \sin(30^\circ)\right)$

$\theta_2 ≈ \arcsin\left(\frac{1}{1.33} \times 0.5\right)$

$\theta_2 ≈ \arcsin(0.3759)$

$\theta_2 ≈ 22.6^\circ$

### Example 2:

A ray of light travels from glass ($$n_1 = 1.5$$) into air ($$n_2 = 1$$). If the angle of incidence is $$45^\circ$$, what is the angle of refraction?

Following the same steps as in Example 1:

$\theta_2 = \arcsin\left(\frac{1.5}{1} \times \sin(45^\circ)\right)$

$\theta_2 ≈ \arcsin(1.06)$

$\theta_2 ≈ 48.7^\circ$

### Example 3:

Light travels from water ($$n_1 = 1.33$$) into diamond ($$n_2 = 2.42$$). If the angle of incidence is $$60^\circ$$, what is the angle of refraction?

Following the same steps as in Example 1:

$\theta_2 = \arcsin\left(\frac{1.33}{2.42} \times \sin(60^\circ)\right)$

$\theta_2 ≈ \arcsin(0.9557)$

$\theta_2 ≈ 72.5^\circ$

### Example 4:

A ray of light travels from diamond ($$n_1 = 2.42$$) into water ($$n_2 = 1.33$$). If the angle of incidence is $$75^\circ$$, what is the angle of refraction?

Following the same steps as in Example 1:

$\theta_2 = \arcsin\left(\frac{2.42}{1.33} \times \sin(75^\circ)\right)$

$\theta_2 ≈ \arcsin(2.50)$

$\theta_2 ≈ 80.7^\circ$
