Flashcards
Total Internal Reflection
Total Internal Reflection
The phenomenon where light traveling from a denser medium to a less dense medium is completely reflected back into the denser medium when the angle of incidence is greater than the critical angle.
Critical Angle
Critical Angle
The angle of incidence at which light traveling from a denser medium to a less dense medium is refracted at an angle of 90 degrees to the boundary.
Total internal reflection scenario
Total internal reflection scenario
A light ray traveling from a medium with a higher refractive index to a medium with a lower refractive index at an angle greater than the critical angle.
Study Notes
Total Internal Reflection
- Total internal reflection occurs when a light ray traveling in a medium strikes the boundary of another medium at an angle greater than the critical angle.
- The critical angle is the angle of incidence above which total internal reflection occurs.
- Critical angle is dependent on the refractive indices of the two media, specifically when a light ray travels from a medium with a higher refractive index to a medium with a lower refractive index.
Scenarios for Total Internal Reflection
- Total internal reflection occurs when a light ray travels from a medium with a higher refractive index to a medium with a lower refractive index.
- It occurs when the angle of incidence is greater than the critical angle in this scenario.
