# Prism Optical Calculator Online

In the realm of physics, particularly in optics, calculating the deviation of light passing through a prism can be challenging. Thankfully, tools like the Prism Optical Calculator simplify this task, making it easy to understand and apply the principles of light refraction.

## Definition

A Prism Optical Calculator is a scientific tool that applies Snell’s law of refraction to calculate the deviation angle of light passing through a prism. This calculator is particularly helpful for students, physicists, and anyone interested in studying the fascinating behavior of light when it interacts with different materials.

## Understanding the Working Calculator

The Calculator operates based on the principles of light refraction. When light passes through a prism, it changes direction or refracts, resulting in a deviation angle. This calculator uses various inputs such as the apex angle of the prism, refractive index of the prism material, angle of incidence, and angle of minimum deviation, to compute the resulting deviation angle.

## The Mathematical Formula Behind the Prism Optical Calculator

The formula used by the Calculator is derived from Snell’s law, and it is expressed as:

θ = A – [(n – 1) × (∠i – ∠A)/∠A].

In this formula, θ represents the deviation angle of light after passing through the prism, A is the apex angle of the prism, n is the refractive index of the prism material, ∠i is the angle of incidence of the light ray, and ∠A is the angle of minimum deviation.

## Example

Let’s take a practical example. Suppose we have a prism with an apex angle of 60 degrees, a refractive index of 1.5, an incidence angle of 45 degrees, and a minimum deviation angle of 30 degrees. Inputting these values into the calculator, it computes the deviation angle, aiding in understanding the behavior of light through the prism.
