Wave Reflection at a Media Interface
A light wave travels from a medium with an index of refraction n₁ to a medium with an index of refraction n₂, where n₂ > n₁. The speeds of the wave in the media are v₁ and v₂, respectively. Which of the following correctly compares the wave speeds and describes the wave reflected at the interface?
A
v₂ < v₁; reflected wave is not inverted
B
v₂ > v₁; reflected wave is inverted
C
v₂ < v₁; reflected wave is inverted
D
v₂ > v₁; reflected wave is not inverted
