Use our advanced angle of refraction calculator that helps you to calculate at which angle a certain beam of light refracts. It also provides complete work for the refractive index, a particular property that refers to the bending of light.
The angle of refraction represents the angle at which the light ray bends when entering one medium to another. The main reason for refraction is that light travels at various speeds via various mediums.
The angle of incidence and angle of refraction is the fundamental concepts.
The relationship is described by Snell’s laws, you can calculate the angle of refraction by the given formula:
Angle of refraction formula = (n₁ * sin(θ₁)) / sin(θ₂)
The angle of incidence and angle of refraction can be predicted by the following consideration:
The refractive index of a medium is fixed and it can’t be changed. You can find what is the angle of refraction of a certain medium by the angle of refraction calculator. It’s important to note that the angle of refraction is dependent on the properties of the two media involved and the angle of incidence.
Suppose the light is entering from air to water, the refractive indexes of the air and water are 1.000293 and 1.333 respectively. If the angle of incidence is 7 degrees, then what is the angle of refraction?
n₁ is the refractive index of medium 1 = 1.000293
n₂ is the refractive index of medium 2 = 1.333
The angle of Incidence (θ₂) = 0.1221731
Formula = sin-1((n₂ * sin(θ₂)) / n₁)
Put values into a formula
θ₁ = sin-1((1.333 * sin(0.1221731)) / 1.000293);
θ₁ = 9.346483
It is not complicated to calculate the angle of refraction with the refraction angle calculator.
Let’s see how?
The angle of refraction of various mediums is given as under:
|Vacuum||1 (by definition)|
|Water at 20 °C||1.333|
The angle of incidence and refraction is different for various mediums, so it is essential to know which wave types refract when crossing from one medium to another.
The refractive index is a dimensionless value and a ratio between the angle of incidence and the angle of refraction.
