The amplitude of an electromagnetic wave remains unchanged when it crosses from a less dense medium to a more dense medium, provided the material is close to electrically neutral, even under strong electromagnetic fields. This principle applies specifically to light waves, which exhibit more complex behavior due to additional factors such as refraction and reflection. Understanding these interactions is crucial for applications in optics and telecommunications.
