Energy in reflected light

Energy in reflected light does not depend on the angle of incidence (option A). When light strikes a surface and reflects off it, the total energy of the reflected light remains constant regardless of the angle at which it strikes (angle of incidence). This principle is a consequence of the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed or transferred. Therefore, whether the angle of incidence is small or large, the energy carried by the reflected light remains the same. This contrasts with other optical phenomena where the angle of incidence does affect outcomes, such as refraction or diffraction, where the direction or pattern of light changes depending on its angle of incidence. Understanding the energy conservation principle in reflection helps in various applications, from designing mirrors to analyzing light interactions with different surfaces.
