Total internal reflection of Light

Question 1

When refraction becomes reflection light…

Answer 1

travels from a more dense medium into a less dense medium e.g. glass to air.

Question 2

Give the three points on Total internal reflection of Light

Answer 2

1. Angle of Incidence is less that the critical angle. (Most of the light is refracted)
2. Angle of Incidence is equal to the critical angle (The refracted ray travels along the boundary)
3. Angle of Incidence is greater than the critical angle (All light is reflected I=R)

Question 3

What does Total Internal Reflection of Light mean?

Answer 3

When refraction becomes reflection light travels from a more dense medium into a less dense medium
