Angle of Incidence and Angle of Refraction

The relationship between the angles of incidence and refraction is explained through Snell’s law (which is known as the law of refraction), which states that the ratio of the sine of the angle of refraction and angle of incidence is always constant and equal to the ratio of phase velocities of the two mediums it is passing through.

• When a ray of light passes through one medium to another it gets deviated. We refer to this phenomenon as the refraction of light.

• The angle of incidence is the angle created at the point of incidence between the incident ray and the normal.
• The angle of refraction is the angle that forms between the refracted ray and the normal.
• Angle of Incidence and angle of refraction lie in different media.

Angle of incidence is the angle created between a ray propagating on a surface and the line normal to the point of occurrence on the same surface. The manner in which the light is reflected back to the observer after it strikes a mirror is an excellent demonstration of how reflection works.

In this article, we will learn more about what the angle of Incidence is, the formula for the angle of incidence, examples related to the angle of incidence, the difference between the angle of incidence and the angle of reflection, and some of the frequently asked questions related to it.
