The angle of incidence is the angle at which a ray of light hits a surface, while the angle of reflection is the angle at which the light is reflected off the surface. The angle of incidence and the angle of reflection are always equal when the surface is flat and smooth.
The angle of refraction is calculated using Snell's law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities of light in the two mediums.
The angle of incidence and angle of refraction are related by Snell's law, also known as the law of refraction. This law states that the angle of incidence and angle of refraction are inversely proportional to the indices of refraction of the two mediums.
The angle of incidence determines the amount of light that is reflected and refracted. When the angle of incidence is small, more light is refracted and less is reflected. As the angle of incidence increases, more light is reflected and less is refracted.
When light travels from one medium to another, the angle of incidence, reflection, and refraction can change. This is due to the difference in the speed of light in each medium, which affects the angles of reflection and refraction according to Snell's law. The angle of incidence will remain the same, but the angle of reflection and refraction will change depending on the mediums involved.
