Total Internal Refraction
Card 1: What is critical angle?
The critical angle is the angle of incident in an optically denser medium for which the angle or refraction is 90o.
The critical angle is the maximum angle of the angle of incident
Card 2: Write 1 equation that relates the critical angle (c) with the refractive index.
Critical angle and Refractive Index
Card 3: What is total internal reflection?
Total Internal Reflection
Total internal reflection is the reflection of light at the boundary of 2 medium where the angle if incident exceeds the critical angle of the medium.
Card 4: State two requirements for total internal reflection to happen.
Requirements for Total Internal Reflection
Card 5: Phenomena Involving Total Internal Reflection - Mirage
Card 6: Phenomena Involving Total Internal Reflection - Rainbow
As we can see in the diagram above, light ray experiences total internal reflection in a water droplet, forming rainbow in the sky.
Card 7: Application of Total Internal Reflection - Optical Fibre
Card 8: Application of Total Internal Reflection - Prism Binocular
Total internal reflection happen in the prisms of a binocular.
Card 9: Application of Total Internal Reflection - Raised Pavement Marker
