When does total internal reflection occur?
When light moves from a less dense to a more dense medium at an angle of incidence less than the critical angle.
When light moves from a more dense to a less dense medium at an angle of incidence greater than the critical angle.
When light moves from a less dense to a more dense medium at any angle.
When light moves from a more dense to a less dense medium at an angle of incidence less than the critical angle.
説明
Total internal reflection occurs when light travels from a more dense medium to a less dense medium at an angle of incidence exceeding the critical angle.
