Angle of deviation calculator helps you find the angle by which light rays change their direction when passing through a prism or any refractive medium, such as glass or water. This is important in optics and physics to understand how light behaves in different materials.
You don’t need to get involved in manual calculations because our Angle of Deviation Calculator handles all the complex math calculations easily. Just provide some necessary inputs, and you're good to go:

Here’s the basic formula for angle of deviation:
D = I + E – A
Where,
Calculating the angle of deviation is quite simple, let's take a look at an example through which you can make your concepts clear. You can also use our angle of deviation calculator for this purpose.
Suppose you have a beam of light entering a prism with an angle of incidence of 45 degrees and an angle of emergence of 30 degrees. The prism itself has an angle of 60 degrees.
you can calculate the angle of deviation by using the formula, such as:
Angle of Deviation = Angle Of Incidence + Angle of Emergence – Angle of Prism
Data we have:
Now apply the formula:
Angle of Deviation = 45 degrees (Angle Of Incidence) + 30 degrees (Angle of Emergence) - 60 degrees (Angle of Prism)
Now, let's calculate it step by step:
Angle of Deviation = 45 degrees + 30 degrees - 60 degrees
Angle of Deviation = 75 degrees - 60 degrees
Angle of Deviation = 15 degrees
So, in this example, the angle of deviation is 15 degrees. This tells you how much the light beam changes direction when it passes through the prism.
The angle between the incident ray and the emergent ray, when a light ray passes through a prism, is known as the Angle of Deviation and it is denoted as delta δ (angle of deviation symbol).
The angle of deviation is affected by the following factors:
The angle of deviation is used in many practical ways, such as:
