A light ray travels through water and reflects off a glass surface back into the water. How do the phases of the incident light and the reflected light compare?.

The light travels through water and gets reflected off on the glass surface into the water. There had been a 180° phase change between the incident and the reflected wave. This is called Total internal reflection(TIR).In total internal reflection, in physics, a ray of light in a medium such as water or glass is completely reflected back into the medium from the surrounding surfaces. This phenomenon occurs when the angle of incidence is greater than a certain critical angle called the critical angle. TIR only occurs when both of the following two conditions are met Light is in a denser medium and is approaching a less dense medium. The angle of incidence should be greater than the so-called critical angle.Thus the phases of incident and reflected light are compared according to the the phenomenon called total internal reflection (TIR).To learn more about total internal reflection, refer: brainly.com/question/13088998#SPJ4
