WebApr 10, 2024 · Reflection of Light. The Laws of Reflection of Light. The angle of incidence is equal to the angle of reflection, The incident ray, the normal to the mirror at the point of incidence, and the reflected ray, all lie in the same plane. Formation of an image by a plane mirror: The image formed by a plane mirror is always virtual and erect. A periscope is a useful example of the law of reflection at work. It’s important that your mirrors are placed at a 45° angle, because light always reflects away from a mirror at the same angle that it hits it. In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle.

WebNov 18, 2024 · A periscope is a device used to see objects over an obstacle. It is made up of two plane mirrors mounted in a long tube. Both mirrors are set parallel to each other at … WebWhen white light strikes the surface of a mirror, it gets reflected in a way that the angle of reflection equals the angle of incidence. There are several mirrors lined along the length of the tube within a kaleidoscope. Thus, light rays hit one mirror surface after the other and several reflections take place within the kaleidoscope.
