Question

The total internal reflection cannot take place when light goes from

• A. Glass to air
• B. Water to glass
• C. Water to air
• D. Glass to water

Answer 1

Answer:

B. Water to glass

• Total Internal Reflection is a specific optical phenomenon that can only happen when two specific conditions are met: • Density Requirement: Light must travel from a denser medium (higher refractive index) to a rarer medium (lower refractive index). • Angle Requirement: The angle of incidence must be greater than the critical angle for that pair of media.
