Study Notes
Refraction of Light
- The bending of light when it passes from one medium to another is primarily governed by the change in speed of light between the two media.
- According to the law of refraction, when light travels from a medium with a lower refractive index to a medium with a higher refractive index, it bends towards the normal.
- Snell's law states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for a given pair of media and is equal to the ratio of the refractive indices of the two media.
- Total internal reflection occurs when the angle of incidence is greater than the critical angle, which is the angle at which the refracted ray grazes the interface between the two media.
- The refractive index of a medium is defined as the ratio of the speed of light in vacuum to the speed of light in the medium.
Refraction of Light
-
The speed of light in a medium governs its bending.
-
When light travels from a medium with a lower refractive index to one with a higher refractive index, it bends towards the normal.
-
Snell's Law states: n₁ sin θ₁ = n₂ sin θ₂, where n is the refractive index, and θ is the angle of incidence/refraction.
-
Total internal reflection occurs when the angle of incidence exceeds the critical angle, causing all light to reflect back into the original medium.
-
The refractive index is defined as the ratio of the speed of light in a vacuum to the speed of light in a medium.
Refraction in Different Languages
- Заломлення (zalomlennya) is the Ukrainian word for refraction.
